Say what you want about the npm ecosystem, but I've found that the most popular libraries to solve a particular problem are almost always the ones with the best documentation. It's natural selection: the ones that are easier to install/use get installed/used more often.

It's to the point where I expect good documentation, and will pretty quickly discard a library if the docs don't look robust on first inspection.

It's sort of bizarre to me that Apple doesn't know this, or at least hasn't acted on it.
