My problem with this, as an occasional JavaScript developer, is "discoverability" (as many others have mentioned). If I decide I need a left-pad function, and search on NPM, how do I choose which one is best? The one with the most downloads? Not always the best indicator of quality; perhaps it's just the oldest.
Not to mention the cognitive overhead of stopping programming, going to NPM, searching/finding/installing the module, then reading the documentation to understand its API. Isn't it simpler to `while (str.length < endLength) str = padChar + str;`? How can there be a bug in that "alternative naive inlined solution"? Either it works or it doesn't!
