Which programming languages the developer nation uses the most? Our data reveal which programming language communities are rising faster than others, which are dropping down the rankings, and which are the new additions to the club! Take a look at our infographic containing key findings from our Developer Economics Q4 2019 survey. 

First of all, let’s all hail for our two years in a row queen, ? JavaScript. The JavaScript community counts more than 12 million users worldwide with an increase of 33% over the last two years.

Among the top programming languages, Python and Kotlin have climbed up faster than any other. With a slow and steady rise Python finally managed to edge out Java, counting 8.4 million users and ranking as the second most used language. When it comes to Machine Learning, Python is the first choice of the developer community, chosen from more than 70% of developers involved in ML. Meanwhile, Kotlin has shown significant growth, it nearly doubled in size in the past two years, finding its way into mobile and AR/VR programming.

After almost 10 years of its launch date and a head to head race with Ruby, Go (or Golang) managed to enter the club of the top 10 most used languages, counting 1.4 million users. Another up and coming language making its way mostly through the AR/VR field is Rust exceeding half of million users.

Let’s not forget that developers are dropping languages all the time. The practice of programming is not static. Even though Swift and Objective-C have been used significantly by the Apple community it seems that the developers are slowly abandoning them. On a similar trend, Ruby and Lua seem to have the biggest decrease (30% & 40%).
