That’s not why JS is a big pile of crap. It’s because the language was not thought through at the beginning (I don’t blame the inventors for that) and because of the web it spread like wildfire and only backwards compatible changes could be made. Even if with all your points in mind the language could be way nicer. My guess is that once wasm/wasi is integrated enough to run websites without JS (dom access, etc.) JS will be like Fortran, Cobol and Telefax - not going away any time soon, but practically obsolete.
