Which programming language is mostly used ?

I don't think this is the kind of question that can be answered by a poll. Generally polls are good for subjective questions like "what's your favorite programming language".

If you want a real answer I'd try a website called www.google.com

By GitHub repository, these are flow of languages from 2014 to 2021.

my guess would be JavaScript, because of the interwebz

Unfortunately, I have removed all content I provided, as I refuse to give free labor to a company that doesn't respect us.

So long, and thanks for all the fish
