I am interested in reading more about their methodology. They seek to rank by “popularity” but thats a very fuzzy term. I expected to see Javascript #1 based on how common it is. Which owes itself to being the only option (outside of the WASM niche) for front end web development, in addition to being fairly general purpose (node, electron, mobile). So im surprised to see it at #5 and less than half the score of python.
For example, search Indeed for software engineer jobs and filter by programming languages. Last I checked JavaScript had far and away the most results. And it becomes clear why - basically any web development position requires it. Python + JS, C# + JS, Ruby + JS, JS (node, ts, etc) + JS, etc.
Again, it depends on how you define “popular.”
