You can definitely mess up with python envs but JS absolutely doesn't have all the features I listed. It doesn't have anything like python's built in power of classes, it's not just having a class syntax which is a thin wrapper around prototypes, it's having metaclasses, class decorators, properties, type comparison that works for inheritance, super(). It also doesn't have sane types/casts.
