Sure, ok. I can buy that this is not actually completely trivial, and that it's worth bringing code to solve this problem in from some other source. Still, it's a shame that the specifics of the way the JavaScript ecosystem has evolved mean that it's commonplace to bring in a <10 line dependency to mitigate an extremely core lack of functionality, rather than have a first-party—or be able to sensibly import a third-party—standard library. I can't think of any other language ecosystem where this is normal.
