Not so long ago, only a few people were considered computer programmers, and we viewed them with awe. In the digital age, we now live in; however, many IT jobs require a solid grasp of a programming language, and sometimes more than one. If you’re trying to advance in your career or change careers completely, and you realize you need to master a programming language, you might wonder which one to learn. After all, it will take time and money to learn the language, so you want to make the right choice from the start.
Several considerations come into play when making your decision, like the difficulty level you’re willing to learn, the skills you already possess that might align with a language, and your reasons for learning a programming language. Whether you want to develop a mobile application, get a certification for programming knowledge, or learn new skills, you need to choose the right programming language to learn. Below you’ll find seven popular programming languages that are in demand right now among employers. For each, you’ll find a little about the language and the complexity, as well as how it is used. However, don’t let the beginner label dissuade you. Even a programming language described as appropriate for a beginner does get more complicated as you become more proficient and experienced in using it.

3. JavaScript and TypeScript
JavaScript is an object-oriented computer programming language commonly used to create interactive effects inside web browsers. Typescript is a superset of JavaScript and adds optional static typing to the language. Alongside HTML and CSS, JavaScript is one of the three core technologies of the World Wide Web. It is also used at the front end of several popular websites like Google, Wikipedia, YouTube, Facebook, and Amazon. Moreover, it is used in popular web frameworks like AngularJS, Node.js, and React.JS. The approximate salary for someone in this role is $72,500.
4. Swift
In March 2017, Swift made it to the top 10 in the monthly TIOBE Index ranking of popular programming languages. Apple developed swift in 2014 for Linux and Mac applications. An open-source programming language that is easy to learn, Swift supports almost everything from programming language Objective-C. It takes less coding compared to other programming languages, and it can be used with IBM Swift Sandbox and IBM Bluemix. Swift is used in popular iOS apps like WordPress, Mozilla Firefox, SoundCloud, and even in the annoying game Flappy Bird. Swift developers earn around $92,000 per year.
5. C#
Developed by Microsoft, C# rose to fame in the 2000s for supporting the concepts of object-oriented programming. It is one of the most powerful programming languages for the .NET framework. Anders Hejlsberg, the creator of C#, says the language is more like C++ than Java. It is best suited for applications on Windows, Android, and iOS as it takes the help of the integrated development environment product, Microsoft Visual C++. C# is used in the backend of several popular websites like Bing, Dell, Visual Studio, and Market Watch. C# developers earn around $91,000 per year.Offer Expires In
6. C (and C++)
C is probably the oldest commonly used programming language, and it is the root of other programming languages such as C#, Java, and JavaScript. C++ is an enhanced version of C. Many developers today skip learning C on its own, while others think learning C first provides a valuable foundation for C++ development. Both languages are widely used in computer science and programming. C and C++ developers can make use of compilers for a wide variety of platforms, making applications developed in these languages largely transportable. Both C and C++ are considered high-performance languages. As such, they are widely used in developing applications where performance is a critical issue, such as client/server applications, commercial products such as Firefox and Adobe, and video games. The average salary is nearly $91,000 per year.
