The gist of the story goes as follow:
- The most popular languages are JavaScript/TypeScript and Python with
roughly 20% of all pull requests each. In effect, if you put
JavaScript/TypeScript and Python together, you get about 40% of all pull
requests.
- Then you get the second tier languages: Java and Scala, C/C++, and Go. They all are in the 10% to 15% range.
- Finally, you have PHP, Ruby and C# that all manage to get about 5% of all pull requests.
- Other languages are typically far below 5%.
