What are the Best Programming Languages to Find a Great Job?

We here present the obviously best programming languages that will also dominate the markets in 2022. It is still not too late to learn any of them since they will be around for at least a decade and learning them will lead to great opportunities. The following programming languages are the most popular ones:

  1. JavaScript
  2. Python
  3. C and C++ and C#
  4. Java
  5. R Language

Let us have a look at these programming languages and their applications in details in the following part of this article.

1. JavaScript

JavaScript is one of the most popular programming languages since its first development and launch. Although most languages may disappear due to new languages, JavaScript will continue to be one of the dominant languages in the coding industry.

The best part of JavaScript is you can use it for both front-end and back-end web development and even in the development of internet of things (IoT) systems using the available frameworks. Consequently, if you are planning to be a full-stack developer, this may be the best language you can start learning.

2. Python

If artificial intelligence technology evolved this far, it is because of Python and its versatile coding style. Unlike JavaScript, Python is used for back-end development. However, it is almost as common as the previous programming language these days.

Today, many functionalities such as Machine Learning to Data Science, Artificial Intelligence to eCommerce technologies are programmed with Python. If you are planning to be a well-paid developer, then you need to know Python very well. It will make everything much easier for you.

Python is an object oriented programming language, therefore, it is important to learn and understand object oriented programming techniques to fully utilize the power of Python.

Today, companies such as Facebook, Uber, and even Google prefer to use Python programming language in their vital technologies and developments.

3. C and C++ and C#

Without a doubt, C and C++ are the most common programming languages used in the programming industries. Did you know that C is also the foundation of many other programming languages? It is so straightforward that no one can write a better or simpler programming language than C and C++.

If you are planning to develop games, then you must know C or C++. Many game engines will also require you to know JavaScript or any of these programming languages to create functions. C and C++ are also essential programming languages to develop embedded systems and microcontroller software and applications.

In spite of the similar naming, C# is a completely different language and it was created by Microsoft, therefore, it is especially powerful for developing Windows applications and well integrated with .NET framework and its rich resources.

4. Java

Every year, we hear rumours that Java is about to die or it will be abandoned by coders. However, every year Java increases its user base or is used for many other new purposes. The best part of Java is its multi and cross-platform use. You can develop Web Applications, Android games or applications, and even scientific applications with Java.

Unlike what most people believe, Java will never die, and it will get stronger every passing year. Considering that it is one of the fundamental programming languages, it may be a good idea to learn this language as well. Java is especially widely utilized in banking and commercial website and applications.

5. R Language

R Language is a relatively new programming language compared to other languages on this list. However, a fresh new language managed to be preferred by many technology giants and universities to develop new technologies based on machine learning and statistics. This is why it is considered to be one of the most popular programming languages of the future, especially in social science related data analysis and applications.


In this article, we briefly review the most popular and demanded programming languages. Of course, there are more programming languages that might be used in more specific areas and technologies. However, learning one of these programming languages and developing projects will definitely be a good choose for people who look for opportunities in technology and software development sectors.
