Most Used Programming Languages ​​in 2021: The world of programming is always evolving, and new programming languages ​​appear every so often. But you know what a programming language is, what are the most used programming languages ​​for this year. We are going to discuss this exciting and passionate topic from the world of computing.

What is a programming language?

A programming language is nothing more than a formal language where a developer writes a series of instructions for a computer to produce various kinds of data.  

Currently, programming goes beyond computers or computers; it can affect various types of devices such as mobile devices such as smartphones or tablets, televisions, and other equipment.

How can developers know which are the most used programming languages?

One of the many ways is through the TIOBE index, which the Eindhoven, Netherlands-based company TIOBE developed. And it is nothing more than a way to measure the most popular programming languages.

This index is priced based on the number of search engine results when the queries have the name of a programming language, covering these searches on Google, Google Blogs, Youtube, Wikipedia, Baidu, MSN, and Yahoo!

However, the PYPL index examines and studies the frequency with which tutorials are requested to learn a certain programming language, deducing that the more searches, the more popular the programming language is.

Top 10 Most Used Programming Languages 2021

According to the PYPL index, the 10 most used programming languages ​​for this year  are reflected below.


Python is one of the most widely used programming languages ​​today

The Python programming language , one of its great advantages, is that its learning curve is low, that is, easy to learn and use, saving time and resources . In addition to open and used in various fields such as Machine Learning, automation and scientific computing. It is also one of the many most used programming languages ​​today.

Python is versatile because it can be used in different fields of computer science , for example, and n the Artificial Intelligence , thanks to Keras and TensorFlow libraries . It is also used for Big Data applications , due to data processing libraries , and is used in web development, due to its Django or Flask frameworks .


Among the most used programming languages ​​Java has a more general purpose

The Java programming language has a more general purpose, it is cross-platform, among other advantages, and multiple applications can be created for different devices .

Its scope is very broad, allowing the development of applications for mobile devices, ATMs, the  Internet of Things (IoT), as well as web pages . 

It was also the default language for creating Android applications, although Kotlin is more widely used for these purposes today, Java is very necessary.


Programming languages ​​such as Typescript, one of the most used, develops both web applications and mobile applications

TypeScript is nothing more than a superset of JavaScript, an open source programming language developed by Microsoft, and released in October 2012 . It is designed for the creation of robust applications . This programming language solves many of the problems of the JavaScript programming language .

It is also a very versatile programming language since it can be used to develop web applications to applications for mobile devices . Making it highly demanded and loved throughout this computing environment.


Most used programming languages ​​that we see in applications such as NetFlix, GitHub, Facebook, Skype, Uber, among others, use JavaScript

The JavaScript programming language, its official launch was in March 1996 and is currently one that is most used by developers and demanded by companies. It is lightweight, cross-platform, and used primarily on the client side. It is one of the most widely used programming languages ​​that is used in front-end and back-end applications, also to develop mobile, server and Internet of Things applications.

It also provides developers with facilities to increase the functionality and flexibility of the applications, thanks to the libraries that can be imported into the code. Many applications that are currently very popular used JavaScript, for example, NetFlix, GitHub, Facebook, Skype, Uber, among others.

C #

C Sharp is widely used in web applications, Windows applications and mobile applications, making it one of the most used programming languages

The C # or C Sharp programming language was launched in 2000 , with 20 years of its launch it is still a language that is used by many developers since it is open source, object-oriented, portability and for having a large community that backs it up . It is also very readable, easy and above all because of the productivity issue .

C Sharp is used in web application development, Windows applications, and mobile applications for both iOS and Android operating systems, game development, and server-side programming.

C / C ++

C ++ has many advantages among them the efficiency of the code being among the most used programming languages

The C ++ programming language was designed by Bjarne Stroustrup in 1979, it is an extension of C with object manipulation and is considered a hybrid language . For years he has had a large community supporting his career in software development.

One of the great advantages of this language is the efficiency of the code and it is popular for creating system and application software. It is used in software infrastructure, desktop applications and servers, etc. Thanks to all its characteristics, it is never missing among the lists of the best programming languages ​​most used worldwide for many years.


PHP is an open source programming language, and widely used for web development

The PHP programming language was created by the Danish-Canadian developer Rasmus Lerdorf in 1994, an acronym forHypertext Preprocessor and is an open source programming language that can be embedded in HTML, it is widely used for web development .

PHP is popular since multiple web pages and portals are developed with this programming language, for example Wikipedia, Sourceforge, Facebook and Sourceforge . Among its main advantages is that it has a very low learning curve, the environments to be developed are easy and quick to configure, it is easy to access and integrate with databases, it is also a multiplatform language and has a very large community that supports it. endorses , as a consequence of that great community it is a language with the greatest use in the world .


R one of the best environments and programming languages ​​oriented to the most used statistical analysis

Among the most used R is an environment and programming language with a perspective to statistical analysis . This language arose from a free software reimplementation of the S language, and is used in scientific research, also in the fields of machine learning,  data mining , among others .

Among its main features are effective handling and storage of data, graphical utilities to visualize the data, it is well developed as it includes conditional jumps, loops, recursive functions, utilities for data input and output , among others.


Objective-C is the main programming language on iOS, Mac OS X, GNUstep, including this Swift list .

The Objective-C programming language was developed by Brad Cox in 1980 . This programming language contains supersets C . Today it is used as the main programming language in iOS, Mac OS , GNUstep, including Swift on this list .

Among the advantages of Objective-C are that it works optimally with C ++ and Objective-C ++, it also has dynamic characteristics in its way of working, such as the swizzling method and it has support when inserting binary frames.


Swift aims to develop applications for iOS and Mac OS

The Swift programming language developed by Apple is among the most widely used programming languages ​​worldwide; with the aim of developing applications for iOS and Mac OS , presented at the Apple Worldwide Developers Conference in 2014. Despite its short history, it has a development community behind it, especially since it became open source . 

Among the advantages of this language that is compatible with Objective-C libraries, you can also access functions of the C programming language . It is also a simple language to program , in this way it attracts more developers, it has properties that make it more secure compared to other languages, and Apple has worked hard to make it very friendly with the developer, in order to make its applications more popular. Swift is one of the easiest programming languages ​​to develop iOS and Mac OS applications
