It has a huge community, of course there will be new things created every week.
But, if it as bad you will not even hear about it, if you hear it is probably good or better on some aspects compared to others, who doesn't want that? do everyone wanted to be stuck with MooTools or JQuery forever?
I mean, you can see clearly why we came from jQuery, to AngularJs, then Angular/React/Vue, there was a need.
I'm not a mobile dev, but I'm pretty sure when you make the front-end in an iOS app, you don't need to learn 3 languages + 2 frameworks + tooling to transpile + type checker + webpack...
Web front-end is completely broken because the foundation (HTML/JS/CSS) is not the right tool for the need.
It is easy to a single company define how they want their platform to be, like iOS, but browsers are a different beast, as every change need to be agreed between several major companies.
Of course we do want new tooling - ES6 and Angular in particular have worked well for me. Where I have some trouble is the tendency of some organizations to adopt these frameworks without considering whether the framework is actually solving a problem the have or expect to have in the near future. YAGNI is very tricky to get right.
I don't think this is a problem unique to JavaScript, however. We see the same sort of thing around technologies. Right now it's ML and Blockchain, earlier it was Cloud and IOT. The industry in general appears to be mostly built on inventing problems that can be solved by the tech, framework, etc. rather than leveraging technology to solve an existing problem.
This may be part of why you're having a hard time finding the problems JavaScript may solve for you. Personally, I find it much easier to follow the "Just In Time Learning" model https://blog.codinghorror.com/keeping-up-and-just-in-time-le.... Find out what parts you need in order to solve your problems, learn how they work, and leave the rest until you need it.
