I'd go further and say that how JS and the web itself has been run over the years has predisposed it to this sort of thing.

JS didn't have a passable stdlib until ES6. It had bugs built into it because Eich was given a stupidly short time window to deliver the first version. Everyone (particularly MS) had (and still sort of do) their own way of interpreting the language. In spite of all of this it became the primary way of developing applications for public consumption.

This led to a bunch of people who wanted to be the 10x JS engineer to solve problems with their own libraries and technologies. None of them really talked, they just threw their packages on NPM's registry without second thought and some gained widespread use just by accident.

Google tried fixing some of this with Dart but chickened out at the last second. TypeScript was designed by someone competent but can't fix the larger cultural issues.

This is what happens when you put SV hubris and "moving fast and breaking things" over doing things the right way.
