I have gripes with some things in the current state of Python, package management particularly, but choosing JavaScript because Python's standard library is "barebones" doesn't really make any sense to me.
I've always found the Python standard library to have tons of useful stuff, and when I'm doing something in JS I often feel like I'm missing my toolbelt or something. Then I install a single npm package to do something simple and it winds up having 350 dependencies.
