I know it's super fashionable to hate on javascript, but I'd be very interested to see a similar rant on another area of software. I'm pretty convinced this is just how the industry works.
The same kind of rant applies to things like automake, but only Javascript has this incredibly high rate of churn. Possibly it's easier to build a new toolchain than to understand someone's existing one.
That's been my annoyance too. Instead of iterating on what's there everyone makes their own thing and tries to reinvent build tools, frameworks, web components, module loaders, transpilers, package mangers etc... It is improving somewhat. Some tools seem to be winning out and clearing the orbit around them but were still in the primeval js solar system with a few planets forming.
+ HTML/Dom limitations
+ Browser fragmentation
+ It's used on the backend as well
+ Nobody is in charge. When someone is in charge, they usually provide the basic tooling and libs - hopefully they do it well - and then you only need ancilliary stuff for special projects. Obviously this can have drawbacks as well, but I'd argue that 2/3 of frameworks are actually trying to solve the same, core problems, just in different ways. They aren't providing 'more' just 'different'.
