A famous example: the is-odd and is-even libraries. It's not the kind of function that would be appropriate for a stdlib in my opinion, and yet developers who presumably don't know about the modulo operator incorporate these libraries into their projects at a high enough rate to engender 700,000/week of downloads. Even with all the basic functions one could hope for being brought into JS' core, there will still be tons of bizarre micro-libraries like these in the npm repository being used by developers who rely on libraries first when it comes to any given feature, because doing so is part of JS culture for the reasons I outlined before.
