The stuff you pointed out could be said of any language, any ecosystem, couldn't it?

There is always some library that is not that well designed that got more popular than it should, little response from certain Github repos, some less than ideal language feature that is there due to historical reasons, important code maintained on a voluntary basis.

Tell me an ecosystem that does not suffer from any of these problems, and I will show you a language that hardly no one uses (when compared to Javascript).

This stuff is inevitable, it comes with the years, due to backwards compatibility, stuff piles up over time. Javascript has resisted particularly well.

If you don't like Javascript, switch to Typescript for me it's the enterprise language of the future, for doing both backend and frontend development.
