In this guide, we’re going to discuss what you need to do to learn Ruby on Rails. We will talk about the basics of Ruby on Rails, what jobs you can get with this skill, and what resources you can use to learn this framework.

What Is Ruby on Rails?

Ruby on Rails (RoR) is a backend web development framework written in the Ruby programming language. This framework follows the model-view-controller architecture and can be used to interface with databases and serve webpages. Ruby on Rails was initially released in August of 2004 by David Heinemeier Hansson.

RoR has become popular because it is efficient for creating backend web architectures. Due to the architecture of Ruby itself, and the design of RoR, you can do more with less code using this framework. In addition, RoR is well documented so there are a lot of examples of how to make the best use of the language.

Jobs that Require Ruby on Rails Skills

The job that requires Ruby on Rails skills the most is backend developer. Many companies looking for backend developers ask for experience specifically with Ruby on Rails. However, not all backend developer positions require Ruby on Rails experience.

You will also use a lot of Ruby on Rails if you join a team as a full stack developer, a position that tackles both the front and backends of a website. This assumes, of course, you join a team that works with Ruby on Rails.

What Companies Use Ruby on Rails?

Are there any examples of companies that actively use Ruby on Rails? Yes, there are plenty. Ruby on Rails has been around for a long time. In the time since the release of RoR, many companies have adopted this framework on their technology stacks.

Here are a few companies that use RoR:

• Dribbble
• Airbnb
• Bloomberg
• GitHub
• Hulu
• Twitter
• SoundCloud
• Kickstarter
• GoodReads

These are only a few names that use Ruby on Rails. Many more companies, large and small, use this technology because it is powerful and has a logical architecture. From the list above, you can see that Ruby on Rails is used by many prestigious names, from book-reviewing sites (GoodReads) and finance companies (Bloomberg) to networking platforms (Dribble).

Salary for Ruby on Rails Developers

According to Glassdoor, the average salary for a Ruby on Rails developer is $75,526 per year. Senior Ruby on Rails developers earn an average of $87,712, which shows that there are clear opportunities for salary increases as you develop more experience building RoR apps. These salaries are commensurate with those offered by a lot of web development jobs.

What Skills Do I Need to Master Ruby on Rails?

To learn Ruby on Rails, you must have a working knowledge of Ruby. RoR is based on the Ruby programming language, after all. If you do not learn Ruby first, you will probably get confused at many points in your journey learning RoR. You may also come to associate with RoR concepts that are actually part of the Ruby language, not the framework.

You will also need a working knowledge of HTML and CSS. Ideally, you will also know JavaScript. You will use these technologies to build the front end of the websites you develop on RoR.

Good knowledge of the model-view-controller architecture is helpful because this is the structure upon which RoR was designed. However, you can learn this architecture when you start researching RoR; the model-view-controller architecture is mentioned a lot in RoR tutorials and courses. 

Where to Learn Ruby on Rails

Ruby on Rails is a well-documented framework and has a strong community of developers who have produced their own content on RoR.

As a result, you have plenty of resources you can choose to learn. Because it can take a while to find a resource that is right for you, we have prepared a list of some of the top RoR learning resources out there:

The tutorials on The Odin Project do not stop at beginner concepts: later you will find guides on advanced forms, APIs, mailers, and more. The tutorials on this site contain detailed explanations of each programming concept as well as code snippets.

A Guide to Learning Ruby on Rails Basics

What topics do beginners to Ruby on Rails need to know? This is an important question to answer because starting at the wrong place can make it more difficult for you to advance your knowledge of RoR. Below we have listed some of the key topics you will need to learn about at the start of your RoR learning journey.

• Architecture: What is Ruby on Rails? Why is the framework used? What architecture is RoR based on? These are all questions you should be able to answer before you start coding with Ruby on Rails.
• Starting a Project: You should learn how to initialize a new project with Ruby on Rails and create a webpage using routes and a controller.
• Views and Controllers: Views and controllers are essential components in an RoR app. You should learn how to create, modify, and delete views and controllers.
• Routes: You should feel comfortable creating and managing routes in a web application.
• Active Record: Once you have created your first application, you should familiarize yourself with the Active Record database system. This includes learning about how to create a migration and an association and run a query. Once you have learned these concepts, you should study how to create many-to-many associations in Active Record.
• Forms: RoR forms are usually built upon Active Record. You should learn how to implement forms in your website once you have set up an Active Record database.

The above topics are a taste of what you will need to know as you begin learning RoR. However, the above list is by no means a complete syllabus. There is a lot to learn about RoR; you will discover more topics to study as you keep learning.

How Long Does it Take to Learn Ruby on Rails?

It usually takes around one or two weeks to feel comfortable with the basics of Ruby on Rails and perhaps about a month before you can set up an application without having to refer too much to notes or guides. Expect to spend about two to four months refining your skills. If you want to use Rails in a job, you will probably need to study it for about six months.

Should I Learn Ruby on Rails?

Ruby on Rails is a popular technology for backend web development, used all around the world by companies like Twitter and GitHub. Rails is based on a model-view-controller framework and gives you the features you need to build powerful web applications.

If you want to become a full stack or a backend web developer, Ruby on Rails is a great skill to have. Not all companies use Ruby on Rails but those that do will almost certainly require at least some experience or projects you can show them to prove your knowledge of the framework.

Even companies that do not use Ruby on Rails will see your knowledge of the framework as an indication of your interest in web development, which may take you further in an interview process.

Spend some time pondering whether you see yourself as a backend or full stack web developer, the people who help create the logic behind web apps. If you do see yourself in this position, learning Ruby on Rails may be a good investment of your time.

In this guide, we’re going to talk about the basics of learning Python. We will start by discussing what Python is and what you should learn about Python. Then, we will spend some time looking at top Python resources online.

What is Python?

Python, released in 1991 by Guido van Rossum, is a general-purpose programming language. This means Python can be and is used for a range of purposes. The language uses the object-oriented architecture which means data can be stored in objects whose structure is based on classes. The language is used for data science, mathematics, software development, and more.

The Python programming language is known for its syntax. Said to resemble English in many ways, the Python syntax is easy to read, which means that beginners can easily understand the contents of a program. In addition to the simple syntax, Python is well documented. You should have no trouble finding an answer to a Python question you have by searching for an answer online.

Jobs that Require Python Skills

There are plenty of jobs that require Python skills. This is because Python has proven to be a powerful language and it was not designed for any one purpose. Whereas R, for instance, was designed specifically for data analysis, Python has no one “best purpose.” Here are a few jobs in which you could apply your Python skills:

• Software engineer
• Back-end web developer
• Full-stack web developer
• Data analyst
• Data scientist
• Data engineer

You may also use your Python skills to a lesser extent in other technical careers, such as systems administrator or database administrator.

What Industries Use Python?

Python is used across industries because the language has a general purpose. You will see tech startups, tech giants, and businesses in other sectors aside from tech using Python in some way. Here is a list of some industries that use Python in some way:

• Healthcare
• Social media
• Gaming and media
• Cybersecurity
• FinTech
• Finance

This list is based on a 2016 survey by HackerRank which tracked which coding languages various types of employers were looking for in prospective employees.

Salary for Python Developers

Developers who are skilled in Python can expect to command an excellent salary. According to PayScale, the average Python Developer earns $79,395 per year. You can expect to earn much more if you specialize in an area related to data science, where Python skills are valued to a greater extent due to the complexity of the work.

The salary you earn will depend on your seniority. Junior Python developers may earn a bit less than the average mentioned above. Senior Python developers, who usually have years of industry experience, may earn significantly more than the salary mentioned above.

What Skills Do I Need to Master Python

To become a proficient Python developer, you do not need any background in programming. A propensity for thinking critically or analytically will go a long way because programming often involves thinking about multiple solutions to a problem and choosing the best one. Problem solving skills will help, too.

As you learn Python, you will naturally pick up more skills that you will need. For instance, if you decide to become a back-end web developer you will probably pick up what you need to know about the architecture of websites as you study.

Where to Learn Python

There are hundreds if not thousands of online courses that cover the Python language. This is reasonable because Python is an incredibly popular language, so much so that many high school computing classes now teach Python. To help you start learning Python, we have compiled a list of top Python courses, which you can find below.

A Guide to Learning Python

The Python programming programming language may be friendly to beginners but that does not mean the language is not used for more advanced purposes. Today, companies like Google, Facebook, Netflix, and Dropbox all use Python.

But what do you need to know to master the basics of Python? We have compiled a short list of topics you should look at as you learn Python:

• Hello World. The “Hello, World!” script is the most basic Python program. This script will introduce you to the Python syntax and get you up and running in the Python programming language.
• Variables and Data Types. You should learn about how numbers, strings, and lists are stored in Python. You should also learn how values are assigned to variables.
• Program Flow. Learn how to use if…else statements to decide when a line of code should and should not run.
• Lists. Spend time reading about how to store and retrieve items from lists. You should also learn how to manipulate the contents of a list.
• Loops and Functions. Learn how to use for loops to automate a repetitive task. You should also learn how to use functions to reduce repetition in your code.
• Dictionaries. Dictionaries are a way of storing data that is mapped to a key name. You need to know how to work with dictionaries and change the values in a dictionary.
• Classes and Objects. You should learn how to create a class in Python and create an object of that class.

These are only a few of the many topics beginners to Python should learn. We also recommend you spend time looking at:

• Manipulating strings
• The operators you can use with if statements
• Working with files
• Lambda functions
• Working with modules
• Debugging

With a solid understanding of all of the concepts mentioned above, you will be on your way to becoming a proficient Python developer.

How Long Does it Take to Learn Python?

Assuming you study for an hour or so a day, you can reasonably learn the basics of Python within a month or so of starting to learn. If you want to become a professional Python developer, expect to spend about six months refining your skills and preparing for the workforce.

These numbers are just estimates. It is impossible to say exactly how long it will take you to learn Python. But because the language is so well-known for being friendly for beginners to learn, the right attitude and a willingness to study will take you a long way.

Should I Learn Python?

The Python programming language is used around the world for data science, web development, systems development, and more. The language is not exclusively used by technology companies: it is not difficult to find a tech-driven company in other industries who use Python in some way.

Python is a great investment in your career. The language is much easier to learn than other programming languages, meaning learning Python can be a good way to get your foot in the door before you explore other technologies. And there are no signs that indicate Python will be any less important in the future.

Ask yourself: do you want to learn how to code? Do you want to work with data, or help build the logic behind websites, or help create software? Asking yourself these sorts of questions will help you make an informed decision about whether you should learn Python.

In this guide, we’re going to aim to answer one question: how do you learn CSS? We will start by talking about the basics of CSS. Then, we will look through a list of resources which you may find helpful in your journey to learning CSS.

What is CSS?

Cascading Style Sheets, or CSS, is the language used to apply styles to a web page. CSS styles can appear in their own document or inside a HTML document. For instance, animated elements on a page, gradients on images, colored backgrounds, and tilted images are all made possible through the use of CSS.

A web page does not need CSS to function but without CSS all web pages would look pretty plain: they would all use the same fonts and be almost devoid of color, except where images are used. HTML is for designing the structure of a web page whereas CSS tells a web page exactly how you want particular elements to appear.

Jobs that Require CSS Skills

Any job in web development will require at least a working knowledge of CSS. If you want to be a front-end web developer, who helps set the design for a website, having a strong understanding of CSS is absolutely essential. Front-end web developers will use CSS on a daily basis. Here are a few job titles you will see where CSS is used:

• Front-end web developer
• Back-end web developer
• Full-stack web developer
• UX/UI designer

While UX/UI designers may not directly write HTML for a website, they do need to be aware of the constraints associated with web design. This means UX/UI designers need to have a good understanding of CSS.

CSS is not exclusive to jobs where you are coding the structure of web pages. A knowledge of CSS may help someone using a content management system improve their site. Knowing a bit of CSS may also help someone convey how they want something to appear on a web page to their colleagues.

What Industries Use CSS?

CSS is used in almost all web development projects. Can you imagine a web page with no styles? The page would just be text. As a result, all industries that make use of the web use CSS in some way and to varying extents. Here are a few examples of the sorts of industries that have websites styled with CSS:

• Banking and financial services companies
• Healthcare organizations
• Governments
• E-commerce providers
• Online game websites
• Insurance providers
• Transport providers

No matter what industry you work in, it is almost certain that a website related to your employer (assuming your employer has one) employs the use of CSS in some way. Of course, many people depend on site generators so they do not write CSS code themselves. But these tools just automatically generate CSS code; they do not escape CSS.

Salary for CSS Developers

The average front-end developer earns a total of $76,929 per year according to Glassdoor. CSS developers are usually called front-end developers. This is because employers expect people who work on the front-end of their websites to have a knowledge of front-end development, the broader field of designing usable websites, of which CSS is only a part.

What Skills Do I Need to Master CSS

To become proficient at using CSS, you will need a basic understanding of the HTML language. Often, people learn CSS alongside HTML because the two languages are so related. A good eye for design is also helpful for learning CSS, but not required. You will pick up a good eye for design as you experiment with styles and figure out for yourself what styles work and what styles are not as good.

Where to Learn CSS

You will find no shortage of resources online for people who want to learn CSS. Many of these resources are positioned to beginners because there is a good demand for front-end web developers and everyone needs to start with the basics. But where should you go to start learning about CSS? We answer this question by listing five top CSS learning resources below.

• Type of Resource: Video

This video, which lasts almost one and a half hours, introduces you to the basics of working with CSS. You will start by changing the color of text and quickly advance onto more complicated topics like setting fonts and sizing images. This course moves very quickly and you will probably find yourself pausing the tutorial quite a bit. But, the content of this video is well-explained and taught in a way that is friendly to people with little to know CSS experience.

A Guide to Learning CSS

When you start learning CSS, you are going to come across a range of technical terms. As a beginner, you will probably find yourself asking: which topics should I learn first? Which topics are essential for beginners to learn? Check out our list below for a guide on some of the concepts you must learn as a beginner to CSS.

• Syntax. You need to know the main components of a CSS rule and how to write your own CSS rule both in a CSS file and in a HTML document.
• Selectors. Selectors let you choose which elements on a web page will be affected by a style rule you write. You should know the basic selectors such as class selectors and ID selectors.
• Borders, Margins, and Padding. You should learn how to apply borders, margins, and padding to an element on a web page. You should also learn about the box model and what this model says about the structure of an element.
• Styling Text. Learn how to apply styles to text. Common styles applied to text include underlines, font changes, new colors, and changing the weight (boldness) of some text. You should also learn how to style links.
• Applying Backgrounds. You should know how to create a colored background on an element. It is also worth knowing how to apply an image background on an element.
• Positioning Elements. You will need to learn how to use CSS to influence the position of an element on a web page. What is the position attribute? What does overflow mean? These are the sorts of questions related to positioning that you should be able to answer.
• Pseudo-classes and Pseudo-elements. You should learn the difference between these two concepts. You need to know how these concepts will let you select elements on a web page.

These concepts will help you build a strong understanding of the CSS language. But, there will always be more to learn: CSS is standardized but that does not mean the language stays the same forever. New techniques are discovered by developers all the time which describe how to best use existing features. Similarly, new features are sometimes added to CSS.

How Long Does It Take to Learn CSS?

You can feasibly start applying styles to a web page within a few hours of learning HTML. But, CSS can get complicated quickly. Expect to spend about six months learning about the various styles you can apply to a rule and getting the hang of formatting and positioning. The practice you do in this time will be enough to help you prepare for a career as a front-end web developer.

Should I Learn CSS?

Learning CSS is a requirement if you want to become a front-end web developer. If you only know HTML, which is used for setting out the structure of a web page, you could design a logical web page but that page would have no styles. On the modern internet, having an aesthetically-pleasing and functional site has become a must-have.

Do you see yourself designing websites? Or do you see yourself turning designs someone else has made into a working web page? If you answered yes to either of these questions, you should consider learning CSS.

If you want to work in a back-end web developer job — where you build the behind-the-scenes logic of a website — you will also need a good understanding of CSS. In short, if you want to pursue any career related to developing websites, you will need to know CSS.

In this guide, we’re going to chat through how you can learn SQL. We will start with the basics: what is SQL and what jobs require SQL? Then, we will move onto where you can go to learn SQL, with reference to books and courses.

What is SQL?

Structured Query Language, or SQL (said as “es-que-el” or “see-quel”), allows you to store information in and access information from a database. SQL allows you to modify individual values in a database or entire rows. You can also remove or add new rows in a database. SQL is an international standard and to this day is one of the fundamental skills for database management.

There are many implementations of SQL. For instance, PostgreSQL, Oracle Database, MySQL, and Microsoft Access all implement SQL, too, but each tool has their own features that database administrators can use. Ultimately, however, all of these databases use a very similar syntax for creating, updating, and deleting records because they all follow the SQL standard.

Jobs that Require SQL Skills

SQL is an essential skill in any job that involves manipulating data. For instance, data scientists need to know SQL because a lot of their work involves analyzing data from databases. Below is a list of the main jobs that require SQL skills:

• Back-end web developer
• Full-stack web developer
• Data analyst
• Data scientist
• Data engineer
• Database administrator
• Systems engineer

These are only a few of the many positions that require knowledge of SQL. All of these positions involve working with data in some way, from administering a database to writing queries to manipulate the contents of a database.

What Industries Use SQL?

SQL is used in most industries that need to store data. Even Microsoft Access, which is used often in business settings and is a drag-and-drop tool, is based on SQL. Below are a few examples of industries that use databases:

• Healthcare
• Manufacturing
• Finance and banking
• Construction
• Online media
• E-commerce

Any industry that needs to keep logs of something could make use of databases. For instance, construction companies may use SQL to keep track of employee data, perhaps through a tool like Microsoft Access. Healthcare companies may use databases to keep track of patient records.

People who use technology powered by SQL may not know it because a lot of database tools abstract away from the language because SQL is not intuitive in many cases where someone may want to use a database.

Salary for SQL Developers

People skilled in SQL can demand excellent salaries. According to Glassdoor, the average database administrator, who will most likely work with SQL every day, earns $78,779 per year. The average data analyst, who is also very likely to work with SQL, earns $62,453 per year. As you get more experience working with data, your salary prospects will improve. Some positions that use SQL, like data scientist, have average salaries above $100,000 per year.

What Skills Do I Need to Master SQL

You do not need to have any knowledge of programming to learn SQL. An understanding of a programming language is helpful, but definitely not required. A good knowledge of basic mathematics is also useful as some database calculations can involve math. But, you can pick up most of what you will need to use as you learn more about SQL.

You can learn SQL even with little knowledge about programming or data science so SQL is a good entry way into data careers. Your SQL skills could take you on to a range of careers in data, if you study and work hard.

Where to Learn SQL

Where can you learn about SQL? SQL has been around for decades so it is easy to find SQL learning resources online. We have compiled a list of some of the top SQL learning resources which you can use to start learning SQL.

This video is intense so you may find yourself pausing and coming back to concepts later. But, the instructor is eloquent in their teaching and walks you through how queries are written and how they work.

A Guide to Learning SQL

What do you need to know to become an SQL developer? That is a good question. SQL can get quite complicated but when you learn the basics you will realise that all the more complicated queries are built up with the same building blocks.

To help you master those building blocks, we have prepared a list of some beginner concepts you need to know:

• Syntax. What is a query? What is a statement? How is a query formatted? What is a row and a column? You should be able to answer these questions before you go any further in your learning.
• SELECT. You should learn how to retrieve information from a database using a SELECT statement.
• WHERE and Filtering. You should know how to use a WHERE clause and the filtering methods (operators) to choose what items you want a query to retrieve, change, or delete.
• UPDATE. UPDATE statements let you change the contents of records in a database. You will need to know how to use an UPDATE statement.
• DELETE. A DELETE statement removes a record from a database. This is an essential statement to know about.
• Aggregate Functions. You should know how to use the COUNT, SUM, MIN, MAX, and AVG functions to retrieve information about the data in a database. You will also need to know how to use the GROUP BY statement with aggregate functions.
• IN and BETWEEN. You will need to know how to use the IN and BETWEEN statements to retrieve records in a particular dataset or between a range.
• Aliases. Aliases make queries easier to read, when used properly. You should feel comfortable using an alias to assign temporary names to tables in a database when you are writing a query.

After you have learned these concepts, you will be on your way to becoming an SQL expert.

How Long Does It Take to Learn SQL?

You can start writing basic SQL statements within an hour or so of starting to study. To master the basics, you should expect to spend about a month studying, assuming you devote one hour a day in that time. If you want to become a professional developer in a field that uses SQL, you will probably need to study for a few months before you will be ready for an entry-level job that requires SQL knowledge.

Should I Learn SQL?

If you want to work in a position that is focused on data — whether that means administering databases or analyzing datasets — having a knowledge of SQL is essential. SQL knowledge is also a requirement in many back-end and full-stack web developer roles, where you will use SQL to store information from web apps.

It will not take you long to learn the basics and with the right investment of time you should have no trouble becoming an expert SQL developer. Your studying will not go unrewarded: the jobs in which SQL is heavily used all pay well. If you see yourself working with data in your career, consider spending some time learning SQL.

How does one go about learning Ruby? That’s a good question. In this guide, we will discuss what you need to learn as a beginner, how Ruby will impact your employability, and what resources you can use to learn this language.

What is Ruby?

Developed by Yukihiro “Matz” Matsumoto, Ruby is a general-purpose programming language. The language was designed to combine functional and imperative programming principles in a way that is easy for developers to understand. Although Ruby has a simple syntax, it is very powerful and has become one of today’s most popular programming languages.

The Ruby language was inspired by languages like Perl and Python, with which Matsumoto was not satisfied. For instance, Matsumoto did not think Python was a “true object-oriented language.” He wanted to build something that was truly object-oriented.

Jobs that Require Ruby Skills

Ruby is a general-purpose programming language which means you can do a lot with it. Today, Ruby is used for software engineering, systems scripting, and, notably, web development. The Ruby on Rails framework, which extends Ruby to make web development simple, has made Ruby an incredibly popular language for web development.

Some jobs that may require Ruby include:

• Full stack web developer
• Backend web developer
• Software developer
• System administrator

These positions can all make use of Ruby to some extent. However, not all jobs under these titles will require Ruby. For instance, as a full stack web developer, you may need to know Python instead of Ruby. With that in mind, because Ruby is so popular, you should have no trouble finding companies that need skilled Ruby developers.

What Companies Use Ruby?

Ruby is one of the most popular programming languages in the world. It is used not only by hobbyist developers but also by a plethora of professionals. Due in large part to the popularity of Ruby on Rails, many big technology companies use Ruby. Here are a few companies that use Ruby as part of their technology stack:

• Stripe
• Vox Media
• Twitch
• Airbnb
• GitHub
• Shopify

These are only a few of the many companies that use Ruby on their teams in some way; there are many others.

Salary for Ruby Developers

Rather than being called “Ruby developers”, it is more common to refer to these professionals according to the field in which they deploy this tool. As such, common job titles include “full stack web developer” or “backend web developer.” The average salaries for people working in these two fields are $105,813 and $101,619, respectively. This shows that if you become proficient in Ruby, you will be able to unlock impressive salaries.

What Skills Do I Need to Master Ruby

You do not need any prior programming experience to learn Ruby. In fact, Ruby is considered quite a friendly language for people new to coding because the syntax is easy to understand. However, a basic knowledge of programming or computer science will go a long way in helping you understand the basics of Ruby.

Having a capacity for analytical thinking is helpful. This is because programming is all about thinking of ways to solve problems and implementing solutions. This process requires a lot of analytical thinking. Fortunately, you can always build your analytical thinking skills as you learn; there is no better way to improve your logical and analytical thinking skills for programming than to practice coding.

At the end of this course, you will be challenged with a capstone project to practice the skills you have learned.

A Guide to Learning Ruby

What topics should beginners to Ruby learn about first? This is the first question you will need to answer. To help you start learning Ruby, we have compiled a list of some key topics beginners need to know.

• Syntax: No matter what programming language you learn, you need to start with the syntax. What is Ruby? What does a line of Ruby code look like? What principles influenced the design of Ruby? These are the sorts of questions you need to answer before you go any further.
• Data Types and Variables: You should learn about the basic data types supported in Ruby and how to assign values to a variable.
• Conditionals and For Loops: Once you know how to use the basic data types and variables, you should research how to use if statements and for loops to control the logic of your programs and reduce repetitive code, respectively.
• Arrays: Arrays store multiple values in one list. You should learn how to create and modify arrays. You will also need to know how to retrieve items from arrays.
• Functions: You should learn how to group code into functions that you can reference throughout your programs.
• Object-Oriented Development: Ruby was designed with object-oriented programming in mind. You should learn the basics of object-oriented programming, the principles upon which this programming paradigm is based, and how to implement objects in your code.

These are a few of the topics that you need to know about to start working with Ruby. However, these topics are only high-level. You need to research the topics above and learn how to apply them. You should not only know what all the above concepts mean but also be able to use them confidently in your programs.

Other topics you may want to research at the start of your Ruby learning journey include:

• Destructuring
• Blocks
• Hashes
• Lambda
• Symbols

Knowledge of all the above concepts will position you well to start writing your own Ruby programs.

How Long Does it Take to Learn Ruby?

You can start writing your first Ruby programs within half an hour of learning the language. To build a good understanding of the basics, you should spend at least two to three weeks studying, assuming you work at least an hour each day. However, if what you want is to land a job in tech, you will probably need to spend about three months studying and refining your knowledge of this language.

Should I Learn Ruby?

Do you see yourself building the logic (backend) behind websites? Or do you see yourself writing systems scripts? If you answer “yes” to any of these questions, then maybe learning Ruby is something you should consider.

Ruby is a vastly popular programming language and you will not have any trouble finding people who know and use the language. With its simple syntax, Ruby has a good learning curve. Even though the language is simple, Ruby is known for being powerful.

Do some research and give Ruby a try. If you like the syntax and think that you could work in a job that uses Ruby, then maybe you should learn it. Finally, keep in mind that Ruby is also a great tool to build your own personal projects.

In this guide, we’re going to talk about how you can learn Git. We will start by explaining what Git is. Then, we will discuss the skills you need to learn and what resources you can use.

What is Git?

Git is a distributed version control system that lets developers keep track of their code. Using Git, developers can see how their code has changed over time, who has made changes to a codebase, and when those changes have been made. This record makes it easy for software development teams to measure each developer’s contribution and figure out when certain features have been introduced to their code.

As soon as a developer clones (downloads) a Git repository to their computer, they can see not only all of the code in the project but also the history of that project. This means that developers can track code without having to depend on any online tools (although there are tools available that make tracking code more visual, such as GitHub).

Because developers can keep their own copies of a project on their computer, they can make changes to a codebase without sharing them until they are ready. One must “push” changes to make them available to the rest of the developers on a project.

Jobs that Require Git Skills

Most jobs that involve programming will either list knowledge of Git as a requirement or a nice-to-have skill. This is because Git is widely used by development teams around the world, from mobile app development to data analysis. Even if you do not know Git, most teams will expect that you learn the basics when you start.

Here are a few jobs where Git skills are used:

• Software developer
• Quality assurance analyst
• Data analyst
• Data engineer
• Web developer
• Database administrator
• Systems administrator

Other developers may use Git too. While there are other methods of version control, Git is so popular you can expect to encounter the tool in almost every programming discipline.

What Industries Use Git?

Git works behind the scenes in programming projects, especially in the technology industry. Outside of the technology industry, Git is still widely used because the platform makes collaborating on code much easier.

Here are a few industries that use Git to store code:

• Social networks
• Car-sharing (e.g. Lyft)
• Government
• Stock brokerage
• Music streaming
• Teaching

Other industries use Git, too, but the above list gives you an idea of the sorts of environments where Git is most commonly used.

What is Git Used For?

Git is used to keep track of programming projects. The Git system is distributed, which means that developers can work on a project independently without changing the main version of the project until they are ready. A central repository, called a “remote” repository, keeps track of changes, but when you pull a repository all of these changes will be logged on your computer.

Here are a few scenarios in which Git can be helpful:

• To measure the contributions of developers on a team.
• To revert back to a previous point in a project’s history and view the codebase at that time.
• To return to a project that has a bug to ensure the bug does not affect the production version of a codebase.

Overall, Git is used for code collaboration. Git makes it easy for developers to see how a project has evolved and gives them the ability to go back in time to see a project in a previous state. 

What Skills Do I Need to Master Git

To learn Git, you will need a basic understanding of at least one programming language. For instance, you may want to learn HTML, CSS, Java, SQL, or Bash. While you could use Git to track regular files, the software is designed to make code collaboration easier. Thus, you cannot effectively learn Git without having some code you are working on that needs to be tracked.

Having a basic understanding of version control systems and how code is developed in professional environments is helpful but not required. You will learn a lot about the architecture of software projects as you learn Git anyway.

Where to Learn Git

Because so many developers use Git, the technology is well documented. A Google search for Git resources will yield many results. Where do you start? What resources are best for beginners? We have reviewed many of these resources and have come up with a list of the best ones for beginners.

A Guide to Learning Git

To start using Git, you will need to learn the basics of its architecture. Then you can go on to using Git in your own project. The best way to learn Git is to start at the very beginning and slowly work your way up to more advanced concepts.

Below is a list of concepts that you should learn as a beginner:

• How Does Git Work?: How do changes become part of the history of a repository? What is a tree? What is branching? How does Git track the history of a project? These are all basic questions you should be able to answer before you delve too deep into Git.
• Setting Up a Repository: With some basic knowledge of Git, you will be ready to start a repository, which is a folder in which Git tracks code. You should learn how to set up a repository from scratch or download a repository from an existing source.
• Pushing a Commit: Once you have set up a repository, you should learn how to add a file to the staging area, add the files in the staging area to a commit, and push a commit to a remote repository.
• Inspecting a Repository: You should know how to view the status of a local repository and how to look at the history of a repository. You should also feel comfortable navigating between different branches in a repository.
• Pulling Changes: You should be able to check for changes on a remote repository and pull those changes to your local copy of the repository.

These features make up the basics of the Git version control system and will take you a long way in your programming career. There are other more advanced features that you may need to learn about as you pursue a career in programming, however. For instance, you will need to learn about diffs, merging, and more.

How Long Does it Take to Learn Git?

You can start using a Git repository and logging your code within a few hours of playing around with Git. You will then need to spend a few weeks learning about more advanced features like viewing the history of a project and using them in practice. To learn enough about Git to use the tool in a professional environment, you will need a few months of experience using the tool.

Should I Learn Git?

Git is used by a large percentage of developers to track contributions to software projects. Git is not exclusively used in any type of programming: data analysis, web developers, software engineers, and more all use Git to track code.

Git is easy to use and will help you keep track of your own code and your contributions to team projects. If you want to pursue a career where you will be writing code, knowing Git is almost essential. Many workplaces list Git as a good-to-have skill. In this case, it is probably ok to learn Git as you go. This is because it does not take too long to learn Git; you can learn this skill on the job.

Good luck on your learning journey!

Learning React is easier if you know where to start and where to go to learn the language. That is why we have written this guide. We want to help you get started on your React learning journey and find the resources you need to thrive. In this guide, you’ll find a range of resources and information about how React can help you in your career.

What is React?

React is a front end web development framework built with JavaScript. React was built by Facebook and released in May 2013. The React framework is based upon components, which are small pieces of code that can be bundled together to create a web page. Components introduce a logical architecture to a website and make creating front ends easier for developers.

The React language uses the principle “learn once, write anywhere.” This benefit speaks to how React can be used with your existing web code, like HTML and CSS, without any interference. You can even use React with the framework React Native to turn your React website into a fully-functional mobile application.

Jobs that Require React Skills

React skills are most commonly used in front end web development. React is a front end web development framework. With that in mind, you may also encounter React in full stack and backend web development. But React will not be used on every engineering team because every business and project has its own tech stack.

Full stack developers operate on both the front end and the backend, so they are likely to use React if the project on which they are working uses React. Backend web developers will not spend much time on the front end but it is useful to have a good understanding of front end technologies anyway. If a backend web developer is building the backend for an app powered by React, they may find themselves occasionally looking at the front end React code.

What Companies Use React?

Although React is only seven years old, many prominent companies are using the technology. The companies that use React range from social networks and streaming sites to online shopping websites.

Here are a few companies that use React:

• Coursera
• Robinhood
• Slack
• LinkedIn
• The New York Times
• Tinder
• Instagram
• Facebook
• Amazon

The above companies are only some of the top businesses that use React; plenty more businesses use it in some way. If you end up pursuing a career in front end web development, you will easily find companies that need your React skills. 

Salary for React Developers

Most companies employ React developers under the title “front end developer.” According to Glassdoor, the average salary for a front end developer is $76,929 per year. Not all of the positions taken into account to calculate that salary will require React as a skill, however.

It is possible to earn much higher salaries as you refine your web development skills. Senior front end developers earn an average of $103,344 per year according to Glassdoor, which is significantly more than the salary for regular front end developers.

What Skills Do I Need to Master React

You will need a good understanding of HTML, CSS, and JavaScript in order to learn React. This means you should feel comfortable writing web pages using all of these languages. React is a framework built with JavaScript and, on a day-to-day basis, you will use React, HTML, CSS, and JavaScript. You should not start learning about React until you feel comfortable with JavaScript.

A good understanding of the web and how web applications are built in professional environments is useful, too. However, you can pick this knowledge up as you learn React.

Where to Learn React

There are many courses and books online to learn React. Some courses cost money whereas others are free. To get you started using React, we have compiled a list of some top React courses that you may want to consider.

MDN Understanding Client-side JavaScript Frameworks

The Mozilla Developer Network has written a few tutorials on how to use various JavaScript frameworks, including React. The first React tutorial walks you through how to get started with this framework. Subsequent tutorials discuss how to create a to-do list that meets certain accessibility requirements.

A Guide to Learning React

The best place to start learning React is to download the create-react-app application. This tool, built by Facebook, makes it easy to set up a server for a React website. The tool also creates a basic architecture for your website so you can start writing your React application immediately. But, after you have set up a project, where do you begin?

Here are a few topics you will need to learn about to become proficient with React:

• React architecture: You will need to know what a React app looks like and the main parts of a React application. Having this knowledge is essential before you move on to other features.
• Components: Components are one of the most important features of the React language. You should learn what components are, why they are used, and how to use a component in your application.
• Props: Props lets you pass data between components. You will need to know how to use props to share data between components and show that data in your application.
• State: The React state value keeps track of values that you set. You can also pass the value of the state between components. You should know how to add an item into the state, retrieve an item from the state, and manipulate the state.
• App lifecycle: React applications go through a lifecycle when they render. You need to learn the main parts of this lifecycle and the order in which each event in the lifecycle happens.
• Functional components: Functional components do not have a state. You should learn how to use functional components and how they compare to regular components.
• Constructors: Constructors let you initialize values in your React application. You should learn how to use constructors to set initial values in React’s state.
• Working with lists: Lists use a concept called keys to identify individual items in the list. You should learn how to write lists in React using keys.

These concepts will give you a solid footing in React. There is a lot more to learn but learning about the above topics will get you started. These are the main features of React which you can expect to encounter in almost every React application you build.

How Long Does it Take to Learn React?

You can start writing code in your first React app within minutes if you use the create-react-app tool. But, you will need to study for at least a month to feel comfortable with the basics of React development. Expect to spend three to six months refining your React skills after that, which is essential if you want to become a professional React developer.

Should I Learn React?

React is a modern web development technology, widely used by development teams around the world. Over the last few years, React has proven that it is here to stay. Through continuous updates and great community support, the language has evolved and more learning resources have become available as people who know React have shared their knowledge.

React is a great skill to know if you want to be a front end web developer. Not every company uses React, but enough do that finding a company that needs an employee with React skills is no problem at all. Companies in industries like news media, social media, and the sharing economy all use React.

Spend some time thinking about whether React is worth learning. Try out React for yourself and see if you like the syntax. If you think React will fit in with your career plan or personal interests, go ahead and start learning it.

How do you learn Angular? That’s a good question. In this learning guide, we’re going to talk about the basics of Angular, what Angular could mean for your career, and where you can go to pick up some Angular development skills.

What is Angular?

Angular, which was released in 2012 by Google, is a development platform built using TypeScript, a program based on JavaScript. Using Angular, developers can manipulate the content of a page. Angular uses the model-view-controller method of programming. A big benefit of Angular is that you can change some parts or your pages without having to change a lot of code to make your pages support the Angular framework.

A big feature of Angular is directives, which let developers control the contents of a web page. Developers can create their own custom directives or use those which are already in Angular such as ng-model. Angular also supports components, like React, which introduces a more modular method of developing web pages. You can use and reuse components anywhere on a page, thus limiting repetition in your code.

Angular, like React, is ready to use out of the box. The Angular environment is easy to set up and as soon as you have installed Angular onto a page you are ready to start using the framework.

Jobs that Require Angular Skills

Angular is a front-end technology. Most people who use Angular are either front-end or full-stack web developers. Both of these job titles involve working a lot with the code that renders the front-end of a website. 

Back-end developers may need to know a bit of Angular in case they need to know exactly how something works on the front-end. But, back-end developers will not use Angular on a day-to-day basis.

What Companies Use Angular?

Companies around the world use the Angular technology to varying degrees. Here are a few companies that use Angular in their technology stacks:

• Google
• Snapchat
• Tinder
• AMazon
• Udemy
• Lyft
• Accenture
• ROBLOX

Angular competes with React, Backbone.js, Vue.js, and other frameworks too. Despite the popularity of these other frameworks, Angular has become a key part of many business’ tech stacks. If you learn Angular, you will have a skill you can use professionally for years to come.

Salary for Angular Developers

If you become an Angular developer, you can reach for a high salary. According to PayScale, the average Angular developer earns $72,248 per year. That is a good amount of money even for a job in technology. Developers in the top 75% earn about $95,000 which shows your Angular knowledge may be worth even more, depending on where you go to work and your seniority within an organization.

What Skills Do I Need to Master Angular

To learn Angular, you will need a strong understanding of JavaScript, the language upon which Angular is built. You should also know a bit about TypeScript, which is the framework Angular is based on. While you may not have to write very complex TypeScript code, this framework will certainly come up in your Angular learning.

In addition, you should feel comfortable with HTML and CSS. This is a given because Angular is a web development technology and all websites must include some HTML (and most sites include CSS, too).

You should also have a legitimate interest in learning Angular. This is not so much of a skill as it is a mindset. If you have not committed to learning Angular, you will find it easy to get distracted from your goal. You need to stay focused on your goal and remember that learning Angular is a journey, not a sprint.

Where to Learn Angular

There are many resources online designed to help budding Angular developers pick up the skills they need to know. Where should you begin learning?

The language, which is said to be “close to hardware,” is efficient, lending itself well to applications such as gaming and building graphical user interfaces where these two benefits are particularly important.

How does one go about learning the C++ language? That’s what we are going to cover in this article. We will discuss what C++ is, where you can go to learn it, and how knowing the language can increase your salary.

What is C++?

C++, initially developed by Bjarne Stroustrup, is a programming language built upon C. C++ was initially released in 1995 and since then has undergone several releases which improved the language. Today, C++ is used widely for gaming, graphical interface programming, and in operating system development.

C++ is taught in university computer science classes around the world because the language incorporates many computer science and programming essential topics. 

Jobs that Require C++ Skills

What jobs need C++ skills? Despite the fact C++ is old and seen by some to be archaic, there are many jobs in which C++ skills are necessary. Here are a few job titles you can expect to ask for C++ skills in some cases:

• Software developer
• Quality assurance analyst
• C++ Developer
• Embedded systems developer
• Game developer

Remember that these are just job titles that may request C++ skills. Not all individual jobs that have these titles will need C++ skills because there are a lot of other languages used in these positions. Nevertheless, C++ is so important in technology that you can find a company that could use your skills under one of the above titles and beyond.

What Companies Use C++?

C++ is widely used by businesses around the world due to the performance offered by the language. Here are a few companies that use C++ in some way:

• NASA
• Facebook
• Microsoft
• Bloomberg
• Oracle
• Mozilla
• PayPal

C++ is particularly advantageous for large-scale applications, such as applications that the sorts of companies listed above develop. Whereas speed may not matter much for a small-scale project, these big companies may depend on C++ to help them keep their infrastructure operating at the desired speed.

Salary for C++ Developers

C++ is not the most intuitive language to learn and takes a long time to master. As a result, C++ developers are well compensated for their work. The average C software developer earns $76,526 per year according to Glassdoor. The salary for a C++ developer varies depending on the type of company at which you go to work as well as the sort of work you will do (i.e. game development, general software development).

What Skills Do I Need to Master C++

You do not need any programming experience to learn C++. With that in mind, having an understanding of C will help you massively in understanding C++. Because C++ is built on C, there are many overlaps between the two languages.

C++ is not recommended to beginners. This is due to the more complex syntax C++ has over various other languages. That does not mean you cannot learn C++ as your first language. You may just need to spend more time learning to get your head around the basic concepts.

Where to Learn C++

Finding a good course or learning resource is crucial to learning C++. But not everyone likes the same resources because everyone learns in a different way. That’s why we have made a list of a few top C++ learning resources which you may want to look at if you decide to learn C++.

While W3Schools does not have as many tutorials on C++ as other sites, each guide is well explained and suited to beginners just learning about C++.

A Guide to Learning C++ Basics

What do you need to know to start writing your own C++ programs? If you do not think about this question, you may end up struggling to figure out where you are. That’s why we have done some research and found the main concepts beginners need to know about.

• Data Types and Syntax. You need to get a feel for what a C++ program looks like and what parts of a C++ program are required in any program. You should also learn about the basic C++ data types, what they mean, and how they are used. 
• Conditionals, Loops, and Functions. Conditionals like if statements let you control what lines of code are run and when. Loops automate repetitive tasks you need to complete. Functions cut down on repetition by putting code you need to reuse in different situations in one place to which you can refer.
• Arrays. Arrays store lists of information. You should feel comfortable working with arrays.
• Objects. C++ incorporates object-oriented programming principles. Indeed, the language was designed to make C object-oriented. You will need to know the basics of object-oriented programming and how C incorporates principles from this paradigm.
• Inheritance. Inheritance lets you share data from different classes. You should spend time familiarizing yourself with the basics of inheritance.
• Pointers and Structures. Pointers store the addresses in which variables are kept. Structures group variables of different data types. You should learn how to use both pointers and structures.

After spending some time learning about these fundamentals, you will be in good shape when it comes time to learning more advanced concepts in C++.

How Long Does It Take to Learn C++?

C++ is not an easy language to learn. You will need to spend at least a month or two learning to get a handle on the basics of C++. That’s only the start of your learning. To learn more advanced features of syntax, you will need to study for three or so more months.

If you want to use C++ for professional use, expect to spend at least six to eight months refining your skills. This amount of study will prepare you for an entry-level position in C++, although even at this point you will still need to do a lot of learning.

Should I Learn C++?

Should you learn C++? That is a question you need to answer for yourself. While there is a lot of buzz around other programming languages, C++ is not going to go away any time soon. The language has been eloquently designed and performs better than many other languages.

If you want to work in games development, C++ is a great skill to have. Many companies also need software engineers who know C++ to help them build their core infrastructure. C++ is a skill that will be useful for years to come, meaning that you can make a career out of C++.

Read about the C++ syntax. Ask other developers what they think about the language. Research whether C++ is likely to meet your personal learning goals. Only then can you make an informed decision about whether C++ is right for you.

In this guide, we’re going to chat about what you need to know about learning PHP. We will start by discussing the basics of PHP and jobs that use PHP skills. Then, we will go on to discuss where you can go to learn about PHP.

What is PHP?

PHP, short for Hypertext Preprocessor, is a scripting language. PHP code can be added to an HTML file to add dynamic features to a website. PHP is commonly used to build web forms and add features to a website that are based on data that can change.

When a PHP file is executed, the content of the file is generated and turned into HTML code. For instance, a news site will retrieve all the stories for a page, generate the page, and then return a full HTML file with the code for that page. This is because browsers cannot read PHP code: they read HTML code.

PHP is popular because it makes adding dynamic features to a website simple. Without having to set up too much infrastructure, you can start to build websites that depend on databases with content that can conveniently change.

Jobs that Require PHP Skills

Most jobs that require PHP skills are related to web development, so you can expect to see the title “web developer” or “PHP” in a lot of jobs where PHP may be required or preferred. Here are a few job titles that may require PHP skills:

• PHP developer
• Front-end web developer
• Back-end web developer
• Database administrator
• WordPress developer

The job of a PHP developer will certainly require knowledge of PHP. Front-end and back-end web development may require knowledge of PHP depending on the technology stack used by your company. Some companies use PHP whereas others may use different technologies instead, like a modern JavaScript stack.

Database administrators are less likely to use PHP on a daily basis. But, if he or she is running a database that interfaces with a PHP application, some knowledge of PHP is needed.

WordPress developers help build websites that use the WordPress content management system. Because WordPress is based on PHP, any custom integrations made on WordPress generally use PHP to some extent. Many businesses need custom features for their WordPress websites so an entire job title has been made out of customizing WordPress sites. These jobs almost always require a knowledge of PHP.

What Companies Use PHP?

PHP is an incredibly powerful tool and so companies around the world have made PHP part of their web development technology stacks. These companies include:

• Facebook
• WordPress
• Lyft
• Tesla Motors
• Etsy
• MasterCard
• Slack

PHP is still a highly relevant skill today, even though there are other languages which are now being used in place of PHP in some cases (i.e. Python Flask). Top companies from social networks to financial services businesses still use PHP today.

Salary for PHP Developers

PHP developers earn impressive salaries. According to Glassdoor, the average PHP developer earns $73,506 per year. The upper bound for PHP developer salaries is $96,000 on Glassdoor. Senior PHP developers, who typically have a few years of experience under their belts, command an average salary of $91,727 per year.

What Skills Do I Need to Master PHP

You should have a working understanding of HTML, CSS, and JavaScript to learn PHP. All three languages are commonly used in web development. Without knowing HTML, CSS, and JavaScript, you will struggle to understand the PHP syntax and how PHP is used on a web page.

Having a good understanding of servers and dynamic content is also helpful. PHP is a server-side technology. However, you can understand the two concepts as you learn PHP, so these concepts are more nice-to-haves than requirements.

Where to Learn PHP

A quick Google search will yield many options for PHP courses and learning resources. But which resources are worth looking at in more depth? To help you find a place to learn PHP, we have compiled a list of some top PHP resources for beginners.

Notes, tips and warnings which will help you develop a deeper understanding of various concepts are annotated on many tutorials.

A Guide to Learning PHP

Where do you start when you want to learn PHP? That is a big question. The best place to start when you learn any programming language is the syntax. Syntax refers to the rules and conventions which govern how a language works, like how you write a line of code in a particular language. Then, you can go on to learning more about the language.

Here are a few topics you should learn about at the start of your PHP journey:

• Data Types, Variables, and Conditionals. Data types refer to the ways in which data can be stored. Variables are unique identifiers for values on a web page. Conditionals decide when certain lines of code are run in a program. You will need to know about all of these concepts before you start to write more advanced web pages.
• Loops, Functions, and Arrays. Loops run the same lines of code multiple times. Functions group lines of code together. Arrays store multiple values in one list. These are all essential beginner topics you should learn.
• Math. A lot of applications involve math in some way. You should learn the basic mathematical operators and how to use them in your web pages.
• Forms. PHP is commonly used to build web forms. You should learn how to create a form in PHP and handle the data you have gathered.
• Session Management. Keep track of sessions in PHP so you can show unique data to different users. Learn how to set cookies and sessions in PHP.
• Using MySQL. PHP developers use MySQL to store data for a web page. Know how to set up a MySQL database, add data to the database, and retrieve data from the database.
• Creating Dynamic Pages with Data: When you feel confident using MySQL, learn how to connect MySQL with your PHP application. Doing so lets you show data from a database on a web page that you have developed.

Learning the above concepts will give you the information you need to write some basic PHP pages. That’s all that matters if you are a beginner: getting your foot in the door and being able to try out coding as soon as possible. You can learn more advanced concepts when you feel confident you have mastered the fundamentals of PHP.

How Long Does It Take to Learn PHP?

PHP does not take too long to learn if you devote the right amount of time to your studies. You will probably spend about two to three months learning the basics of the language and MySQL, which is often used to store data with PHP applications. A few months of additional study will position you well for an entry-level job that requires knowledge of PHP.

Should I Learn PHP?

PHP may be an older web development technology but the language is by no means archaic: a large percentage of the sites on the internet today use PHP. This is because WordPress, the most popular content management system in the world, was written using PHP.

There is no escaping PHP on the modern web. Plenty of companies in all sorts of industries have websites built on PHP who need an expert developer to help them improve their sites. PHP offers not only good job prospects but high salaries, too.

Learning PHP is a big commitment, like learning any programming language. Take some time to ask yourself why you are interested in PHP. Try the language out. If you like using PHP and think the language could help you in your career, there is no reason why you should not set out to become proficient in the language.
