Every software development is built thankfully to the programming languages. As we all know, GitHub is the world’s largest code treasury. In a search which requires examining how languages are used on GitHub, you may build up the popularity of all the programming languages among developers, and you can learn more about their qualities.

So, let’s have a look at the top programming languages used by GitHub Repo Contributors in 2021. 


It is well-known that JavaScript is one of the most used languages. In the previous year there were around 4 million developers who joined this community, which is the biggest growth rate across all programming languages. Although, among software domains where JavaScript is not a desirable programming language, there is a survey which revealed that approximately a fourth of developers use it in their projects.


For a long time now, Python has long been one of the most popular programming languages. It was blown up to second place as the top programming language used by GitHub repo contributors in 2021. It is an expanding programming language for machine learning and data research. Because of its simple syntax and library support, all developers fasly became popular and sought after.


According to GitHub’s research for the last two years Java became the third most used programming language. Java was invented by James Gosling and it was released on May 23, 1995. It shares some low-level features with C and C++ but it is a high-level language for web applications.


Go is developed by Google and is an excellent choice for today’s microservices designs. This year is the first time the Go programming language  has been included in the list of GitHub contributors. It is lightweight and well-suited which makes it really convenient and easy to use.


TypeScript is developed by Microsoft and it is one of the most fast-growing programming languages. Its functionality is similar to JavaScript and it has some new features such as enumeration type and floating numbers. It was released earlier this year.


C++ is the sixth programming language on GitHub’s list. It can create operating systems, games and even more and that’s why it is one of the most used languages which had seen an increase in ranking since last year.


Ruby is a high-level programming language which emphasizes on productivity. One of its best features is the attractive syntax it possesses which makes it easy to read and write. This year it is placed at seventh place among the most used programming languages which are used by GitHub contributors.


PHP is one of the most frequently used scripting languages.The previous year it was ranked on the fourth place but now it has won the eight position. PHP is used to create static web pages and apps as well as dynamic websites.


C# is a safe and an object-oriented programming language which derives from the C family of languages. In Stack Overflow Developers’s opinion the language is really popular and convenient to use. These days Microsoft released .NET 5.0 which is the latest major edition of its .NET development platform and it  includes a new version of the C# language, C# 9.


Last year C was ranked in eight place but now it is in tenth among GitHub’s list. It is an  extensively utilised programming language in various applications, including generating and building databases, creating compilers, and developing IoT apps.
