1000% that's why I said "Fair points"

I consider npm to be part of "the interface of JavaScript" and to your point it's one of the strongest reasons beyond performance to use Node over some other dynamic language like Ruby or PHP.

My point is that Python is not used because it's highly performant - it's basically the slowest language there is. But because people like the syntax and the library ecosystem (AKA the interface to the language)
