Most Popular Technologies Based on StackOverflow Survey

Every year StackOverflow asks developers community about everything from their favorite technologies to their job preferences. This year over 100,000 developers took their survey.

According to Annual Developer Survey results, for the sixth year in a row, JavaScript is the most commonly used programming language. Python has risen in the ranks, surpassing C# this year, much like it surpassed PHP last year. Python has a solid claim to being the fastest-growing major programming language.

We see close alignment in the technology choices of professional developers and the developer population overall.



Stack Overflow’s co-founder and popular programming figure Jeff Atwood famously said:

Any application that can be written in JavaScript will eventually be written in JavaScript.

JavaScript is a cross-platfom language that allows developing desktop, mobile and web applications. Three of the four most popular frameworks are JavaScript-based. React.js, Angular.js and Vue.js. are among most commonly used.

The React library was developed by Facebook. It allows developing mobile apps, websites, and single-page applications. This library is much easier to learn than Angular.

Angular, in its turn, was created by Google. It is constantly updated and improved. As for now, Google is working on Angular 4 which is supposed to replace Angular 2. In general, this library is good for web enterprise apps.

In addition to the above libraries, the very popular library is node.js. It allows developing a server part using Javascript. This is the best solution if you want to make a back-end by JS.

JavaScript is universal and quite flexible language. That is why it is on the top of all other languages for several years in a row.


It is a must for every developer to know the basics of SQL. This language allows to manage data in a relational database which is used by most websites.


Java is one of the fastest and most secure languages. Java may seem difficult to learn for beginners. Nevertheless, it is worth learning because Android apps are developed in Java. Popular career paths with Java are backend developer, big data developer, embedded systems engineer, or Android developer.


Over years, python is gaining its popularity. There are several main advantages: it is laconic, understandable, and easy to learn and support. Python is a general purpose language which you can find almost anywhere today. You’ll find it in web applications, desktop apps, network servers, machine learning, media tools and more.


C# is one of the most advanced and convenient programming languages. It is the main development language for the Microsoft .NET platform. C# is very similar to Java, but still has a number of advantages. It’s worth mentioning separately that C# is more difficult to learn than Java. This is not the best solution for beginners.


PHP is commonly used for websites development. According to statictis, over 240 million websites are developed in PHP. PHP has good flexibility and performance. It can be used for small business websites, as well as for large projects with high load. The main disadvantages are the lack of the ability to develop desktop applications and server components. Over years, PHP is losing its popularity.


This language may be difficult for beginners. That’s why many try to avoid it. Nevertheless, due to its high performing, C++ may be used for almost any purpose.

Instead of conclusion, it is worth mentioning one more programming language. Swift is quite young language created in 2014 by Apple. This language is used for developing applications for iOS and macOS. In comparison to Objective-C, which has been used before, Swift is improved in terms of usability and performance.
