Good, IT specialists will be in great search this year too! And those who want a new, financially attractive job can move toward programming. Developers who know the programming languages currently requested will certainly have interesting work contracts for the future. As there are currently over 700 programming languages, we have decided to present a top 10 recently published on It should be noted that the top of the most demanded programming languages changes every year, yet some of them manage to trend for years in a row. 

  1. Python – is a high-level, general-purpose programming language that has been designed to be extremely easy to read and understand. Thus, Python has become one of the most popular programming languages, especially in the back-end web development. This language has developed a lot in recent years and is constantly growing, due to the utility in AI, artificial intelligence, data science and machine learning. Python can be used to create desktop applications, web applications, or frameworks. It's a multifunctional language used by companies like Google or Yahoo! 
  2.  R – is a free programming language and software environment for statistical and graphics calculations. R-language is widely used among statisticians and data miners for statistical software development and data analysis. Today R is already more popular than SQL, it is actively used in business organizations, research and universities. 
  3. JavaScript – is one of the most popular programming languages of the present. It is top of the developers' preferences each year and is unlikely to lose the position in the future. In addition to HTML and CSS, JavaScript is one of the fundamental technologies of the Internet. JavaScript is usually used in front-end web development, but it can also be used in back-end web development. In addition to interactive websites, JavaScript is used to create chatbots, system scripts as well as games. 
  4. Java – it is the most popular but also the most stable programming language in the world. Java was designed to work on a wide variety of devices, from smartphones and computers to smart TVs. This programming language is object-oriented and can be used for desktop applications with a graphical interface, mobile applications, or applications and web servers. Compatible with many platforms, Java programming has applications in almost any industry. 
  5.  PHP – is one of the most important open-source and server-side web programming languages, with versions available for most web servers and all operating systems. PHP is widely used in the development of web pages and applications. Organizations such as Facebook, Yahoo, and Mail Chimp use the PHP programming language. 
  6. C# (C sharp) – is a targeted-object programming language designed as a competitor to Java. Like this, C# is a derivative of the C++ programming language. Applications for Windows, as well as web or mobile applications, can be created using the C# programming language. C# has the fastest evolution and is one of the languages used to create applications in the .net framework. 
  7. C++ – is one of the most stable, efficient and adaptable programming languages. The C++ programming language is a more up-to-date version of the C language It is also called a hybrid language, being a combination of a procedural language and a targeted programming language-object. C++  it is generally used to create desktop applications, web and mobile solutions, video games, and embedded systems. Adobe, Microsoft, Google and much more use C ++. 
  8. Scale – is a multi-paradigm programming language that combines object-oriented programming concepts and functional programming. The scale is widely used in web development, data analysis and data flow. The language runs on the Java platform, the compiler generating bypass compatible with existing Java programs. Organizations that implement the scale in their business include the New York Times and 
  9. SWIFT – is an object-oriented programming language that is compatible with Apple operating systems and frameworks. The popularity of SWIFT is due to simplicity in use, stability, and high level of security, but also to the fact that it is open-source. Most of the elements in SWIFT are inspired by C and objective-C, but also from Rust, Haskell, Ruby, Python. Currently, this programming language is used to develop applications for Apple, macOS, iOS, watchOS, and tvOS devices. 
  10. Kotlin – was created to work well with Java, but it is a more concise programming language, through which programming issues can be resolved with just a few lines of code. Kotlin became extremely popular, especially after Google announced it as the official programming language for Android applications. Since Android is the most sold mobile operating system, the fact that Kotlin is one of the most popular programming languages we need to study in 2021 should not surprise us.
