Once upon a time, the world of computer programming was a mysterious and exclusive place. Only a select handful of people were considered computer programmers with cutting-edge coding skills. Today, many IT jobs require a solid grasp of the top programming languages, and yes, we mean more than one. 

If your plans to advance your career or change careers completely requires you 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.

When making your decision, you should bear several considerations in mind, like the difficulty level you’re willing to tackle, the programming language knowledge you already possess that meshes with your existing coding skills, or your reasons for learning a top programming language. 

Whether you want to develop a mobile application, get certification for programming knowledge, or learn new skills, you need to learn the right programming language. Below you’ll learn about the best programming languages in demand among employers in 2022. You’ll be briefed about the details of each language, its complexity, and how it is used.

What is a Programming Language? 

A programming language is a way for programmers (developers) to communicate with computers. Programming languages consist of a set of rules that allows string values to be converted into various ways of generating machine code, or, in the case of visual programming languages, graphical elements.

Generally speaking, a program is a set of instructions written in a particular language (C, C++, Java, Python) to achieve a particular task.

What are the Best Programming Languages to Learn in 2022?

What coding & programming language should i learn? JavaScript and Python, two of the most popular languages in the startup industry, are in high demand. Most startups use Python-based backend frameworks such as Django (Python), Flask (Python), and NodeJS (JavaScript). These languages are also considered to be the best programming languages to learn for beginners.

Below is a list of the most popular programming languages that will be in demand in 2022.

1. Javascript

JavaScript is a high-level programming language that is one of the core technologies of the World Wide Web. It is used as a client-side programming language by 97.8 percent of all websites. JavaScript was originally used only to develop web browsers, but they are now used for server-side website deployments and non-web browser applications as well. 

Javascript was created in 1995 and was initially known as LiveScript. However, Java was a very popular language at that time, so it was advertised as a “younger brother” of Java. As it evolved over time, JavaScript became a fully independent language. Nowadays, JavaScript is often confused with Java, and although there are some similarities between them, the two languages are distinct.

10. Ruby

If you want to start with a language that is known for being relatively simple to learn, consider Ruby. Developed in the 1990s, it was designed to have a more human-friendly syntax while still being flexible from the standpoint of its object-oriented architecture that supports procedural and functional programming notation. A web-application framework that is implemented in Ruby is Ruby on Rails (“RoR”). Ruby developers tout it for being an easy language to write in and also for the relatively short learning time required. These attributes have led to a large community of Ruby developers and a growing interest in the language among beginning developers. The average salary for a Ruby developer is around $121,000 per year.

11. C and C++

C is probably the oldest and popular programming language and 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 like Firefox and Adobe, and video games. C and C++ developers earn an average of $118,366 each year.

Level:

C – Intermediate to Advanced 

C++ – Beginner to Intermediate

Skills Needed:

Problem-solving, basic computer knowledge. As C and C++ are geared toward low-level management of computer resources,  knowledge of computer functions such as memory management is beneficial.

Platform:

Mobile, Desktop, Embedded

Popularity Among Programmers:

  • C – There has been a higher migration from C to C++
  • C++ – One of the world’s most popular languages

Benefits:

  • C – Used to learn the fundamentals of programming at the lowest (hardware) level
  • C++ – allows for a much higher “control” than other languages

Downsides:

  • C – Coding in C is stricter, not very beginner-friendly language, the steeper learning curve
  • C++ – A bit more challenging to pick up and become productive with than C (and even more so than Java)

Degree of Use:

  • C – One of the most widely used
  • C++ – Widely used

Annual Salary Projection:

$118,366

12. Matlab

Matlab is a proprietary programming language owned by MathWorks and originally released in the mid-1980s. It is built specifically for use by scientists and engineers.

Programmers use Matlab to build machine learning and deep learning applications. Matlab-based programs enable users to analyze data, create algorithms, process images, and verify research.

Generally, Matlab is easier to learn than other programming languages on our list. MathWorks’ website has an extensive section dedicated to answering questions about Matlab.

Annual Salary Projection:

$100,766

13. TypeScript

TypeScript is a newcomer to top programming language lists, but it’s making headway. It was developed in 2012 by Microsoft and is a typed version of JavaScript that is well suited for large code bases. TypeScript is used to create JavaScript-based projects with typing in both client-side and server-side development, making useful for catching errors and preventing systemic issues.

TypeScript was named “most adopted tech” in the 2021 State of JavaScript Survey. TypeScript developers typically earn an annual average of $75,199.
