Most data you find on this will be very unreliable. Also, what is "JS"? Frontend? Backend?
If there even are answers to this question, they're not going to be good enough to base any decisions on.
Also, you left some of the most popular language: Java, C, C++, C#, PHP, etc. Python and Ruby are still niche languages compared to Java and C-family languages.
