I'd prefer Eiffel or Oberon, but almost anything is better than ES6. I just wish there was some kind of standard library movement to coincide with it, but even MS seems okay with left-pad.
I keep hearing this complaint, and at the same time I'm wondering why it's a big problem. So you can't find 3rd party libraries that are good enough to fill in the void from the lack of a good standard library?
Given all the constraints, it’s highly unlikely that you find something consistent.
That's a strange choice of example to highlight the sparseness of the standard library.
