IMO JS and its spinoffs made mostly the best choices for an interpreted language. The bad parts are pretty inconsequential, and the good parts are important things other langs didn't do well. Even Rust took after how it does async and package management.

Better than Python which also recently started copying over JS decisions, except that Py was easier to use with C libs from the start which made it capture math/data/science usage earlier.

I would certainly not consider package management to be a good part of JavaScript (or Rust, for that matter).
