Aspiring developer? Get a jump start on your peers. Here's our list of the highest-paying programming languages to learn, and where you can learn them for free online.

Entering the job market for the first time or changing careers can be a daunting task. The job landscape has changed drastically in the last several decades, and you may be wondering what the most lucrative job skills are for the modern career hunter. The secret, it seems, is in tech, where computer programmers and developers are not only in high demand, but are also pulling in some seriously superb salaries.

In fact, according to the Bureau of Labor Statistics, software developers have a bright future ahead with a projected employment growth of 31 percent for app developers and 24 percent for general software developers by the year 2026. As a developer, you can anticipate a fantastic financial future - the average median salary for a developer surpasses six figures at $103,560 annually.

There are plenty of schools where you can learn various coding languages and get set on the path towards a job in software development.

Swift is a programming language invented by Apple for building programs on iOS, macOS, watchOS, and tvOS. It was released in 2014 and is currently on its fourth version. One of the main advantages of Swift is that it uses much cleaner syntax than other languages, making writing code significantly easier as it more closely resembles the English language. 

The code itself is safe by design, but also runs incredibly efficiently. You can find the code open source on Swift.org where developers across the globe are constantly upgrading and developing new applications for Swift.

By learning Swift, you’ll be able to apply for jobs as an entry-level iOS developer, which not only pays well, but is also an especially highly sought-after skill. Check out these websites where you can learn Swift for free online:

C++ is another useful general purpose language that has a history reaching all the way back to 1979. While it is not inherently a safe language — the C++ website recommends that people really know what they’re doing to use it — it is remarkably fast. 

As it is both an open language and one of the most commonly used worldwide, it translates easily to many different platforms with little to no changes.

Folks with knowledge of C++ can find work as software developers and in IT positions. Learn C++ on these sites for free:

  • Learn-C++. Offers a free interactive tutorial to teach you the basics and some advanced principles of C++.

Java

Entry Level Developer with Java Skills Salary: $66,417

Java has been around since 1995 and remains incredibly popular today. It’s relatively simple to learn and its main benefit is that it is platform-independent, meaning it can be moved between computers running on different operating systems. 

Their motto is “write once, run anywhere,” (WORA), an advantage that makes knowing Java an especially useful skill. Java is currently the number one platform for development in the cloud which is important to note because cloud engineers and developers can earn even higher salaries than regular software developers. 

It was also named the most popular coding language by Inc.com and currently ranks first on the TIOBE Index for most popular programming languages..

Knowing Java will make you quite versatile, especially since it can run across platforms. Here are some places you can learn Java for free online:

  • LearnJava. This interactive tutorial is great for people of all skill levels and lets you implement lessons with their hands-on, in-browser coding program.

Perl

Entry Level Developer with Perl Skills Salary: $65,430

Perl was initially developed in 1987 and is currently on its fifth version. It’s one of the most popular coding languages used for web applications. One of the biggest advantages of Perl is that it’s a complete language, meaning it implements various pieces of several different languages into one easy-to-use, comprehensive programming language. 

This means that you can generally accomplish most tasks using only Perl, rather than swapping between languages, all of which you’d need to learn. 

Because it’s a complete language, it’s definitely a useful skill to have, but it should be noted that Perl has declined in popularity in recent years. Still, Perl developers can make a great salary and should be able to find work. Learn Perl for free on these sites:

  • Learn-Perl. Another free interactive tutorial from the Learn series which teaches you the basics and lets you practice with their in-browser coding program.

C#

Entry Level Developer with C# Skills Salary: $62,032

C# was developed by Microsoft in 2000 and is a general-purpose, object-oriented language. It’s typically used for backend programming and automation in Windows. Because it’s fairly close to Java, it’s a great language to learn alongside or in addition to Java, making you much more hire-able. 

One of the greatest advantages of C# is its safety — because it’s stored on your server in a binary, hackers won’t automatically have access to your source code in the event of a breach.

Because C# is typically used for backend development, and because backend developers tend to out-earn their front-end counterparts, it’s definitely a lucrative language to learn. Check out these sites to learn C# for free:

  • LearnCS. You guessed it! This program also has a C# course complete with their interactive coding program and useful tutorials on the basics of C#.
  • Code Easy. Offers free beginner and intermediate courses on C#. It employs adventure storytelling and interactive tasks to make learning the language fun.

Ruby

Entry Level Developer with Ruby Skills: $60,157

Ruby first appeared in 1995 and has gained popularity ever since. One of the main reasons for its popularity is that it’s quick to write, with some statistics suggesting it’s up to 30 to 40 percent faster to develop projects with Ruby than with other languages. It’s object-oriented and because of its ease of use, it’s much simpler to avoid bugs and create high-quality code. Ruby is a general purpose language, but it most commonly used for web applications.

Most importantly, Ruby is the programming language used in Ruby on Rails, the web application framework that is implemented in Ruby. Ruby on Rails is used frequently

Although many coders have joked that Ruby is dead, it still ranks 15th of all the most popular coding languages on the TIOBE index and is a great skill to have due to its speediness. Here are some sites where you can learn Ruby for free:

  • LearnRuby. Another great tutorial from the Learn series, get the basics of Ruby and hand-on experience with this course.
  • Codecademy. Take their free tutorial on Ruby which ends with an interactive final project.

R

Entry Level Programmer Analyst with R Skills Salary: $58,973

R is a language that’s been around since 1993. Although R is a general purpose language, it is most often used for data analysis, simulation, graphics, and statistical modeling. R is not the simplest language to use and because of its typical applications, it’s less suited for developers than it is for folks who are interested in going into data science and other analytical fields. It is, however, a cross-platform language and interacts well with other statistical analysis tools.

Because it’s a data science-driven language, it’s a great skill to have if you’re on that track. And, data scientists tend to earn quite a bit more than developers, starting at $87,629 annually. Here are some places where you can learn R for free:

  • Data Camp. Offers a free four-hour introductory course in R. It’s an especially good place to start if you want to pursue one of Data Camp’s R programming or data science tracks.
  • edX. Harvard Extension School developed Data Science: R Basics course which you can take free on edX. It uses real-world data sets to help you learn R by problem solving.

JavaScript

Entry Level Developer with JavaScript Skills: $55,378

JavaScript first appeared in 1995 and was originally developed for NetScape Navigator - remember that? It’s typically used in website design as a way to make your site more interactive and user-friendly, and is often deployed in conjunction with HTML and CSS. 

Because it operates on the client side, it allows sites to run much more quickly and reduces overload on servers. It’s incredibly versatile, and is popular in part because it can produce the same result on essentially all modern browsers.

Because it’s most often used with other languages, it’s a good idea to learn the basics of coding, especially HTML and CSS, before embarking on a career in JavaScript. However, these sites can help you learn the language for free:

PHP

Entry Level Developer with PHP Skills Salary: $50,260

PHP didn’t start out as a programming language, but grew that way organically as creator Rasmus Lerdorf continued to tinker with it and implement it on his own personal website - hence, the name Personal Homepage/Forms Interpreter (PHP/FI). 

PHP is a general purpose language but is generally used for server-side scripting, one crucial piece of backend developing. Its main advantage is its speed, which is why many people opt to use PHP as part of their backend programming.

Again, backend developers tend to outearn their front-end peers, so having knowledge of PHP could set you on a path for a well-paying backend position. Learn PHP for free on these websites:

  • LearnPHP. Check out the Learn series on PHP for an in-depth and interactive tutorial on the language.
  • Udemy. Offers a free Beginner PHP and MySQL Tutorial which is a great way to learn to develop web apps while learning two useful skills. The course contains over 10 hours of video lectures, and you’ll get a free certificate upon completion.

  • SoloLearn. Like their other programs, you can study PHP online or through their app and complete challenges to open more new interactive levels as you unlock more achievements.
  • Code Course. Has 125 different video courses on PHP-related subjects.
  • Hacking with PHP. This site offers a 25 chapter tutorial that can introduce you to the basics of PHP and get you started on some more advanced subjects.
  • Home and Learn. Offers a free tutorial on PHP. Users should have a base knowledge of HTML before hopping into this particular program.

You could be on your way to a much more lucrative career in web, app, or software development in just a few short weeks. And, with this guide, you’ll be able to get that new career off the ground with almost no expenses upfront. So, what are you waiting for? Pick your language and get coding!
