That's what I assume people mean, because they can't mean trivial stuff like "left-pad" and "is-even" because why would that be part of any language's standard library?
Weird that the JS community relies entirely on external libraries with arbitrarily deep and fragile dependency trees that default fail to wrecking the entire web because JS "doesn't have a stdlib" for this sort of thing then. ¯\_(ツ)_/¯
It is. Though in their defence, I think this api was added after the leftpad fiasco.
Also not many people seem to know this, but in the aftermath of leftpad being pulled from npm, npmjs changed their policy to disallow module authors from ever pulling old packages, outside a few very exceptional circumstances. The leftpad fiasco can’t happen again.
