Now try to take a look at some real languages. At the languages with well-defined, simple, orthogonal semantics. And, no, JavaScript is nowhere near any "powerfull, expressive language". It is embarrasingly low level for a supposedly scripting language and it does not provide any powerful productivity features whatsoever. JS is also a nightmare for the implementers, it does not have a sane specification, therefore most of the tooling is not comprehensive.
