I'm trying not to sound all gatekeep-y, but I think this is the downside of a low barrier to entry. JavaScript has attracted a lot of programmers who just don't have the experience to manage things like maintainability, dependency management, or non-breaking upgrades. Some of them go on to create things that are great in the moment and deservedly become popular, but then fall prey to problems in these areas as they age. The same has happened to various extents and at various times with Python, Ruby, PHP, and so on.

On balance lower barrier to entry is a good thing, but it does have characteristic problems too. In fact, I'd say fault lies partly with more experienced programmers and particularly packagers, who often tend toward avoidance (or worse) instead of helping these newer ecosystems avoid known pitfalls.
