JavaScript has the unfortunate situation of having years upon years of terrible standard library design, leading to people building lots of small libraries on top of those libraries to get things that were basic functionality in other languages.

Then people started stacking more and more things on top of those libraries, creating a giant dependency morass of microdependencies that larger frameworks are now build on top of. And because all these frameworks do things just different enough from each other, every larger library that a dev would want to integrate with those frameworks now needs a specialized version to work with those frameworks.

In most languages, if you want to know how something works, you can usually dig into your dependency tree and by the time you hit the stdlib's optimization spaghetti/language internals, you'll probably have figured out what's causing your snag/what the library is expecting out of you. In JavaScript, you hit the dependency morass and have to give up. Most competent devs then decide to pick another language.

You can write very legible JavaScript these days, even without a framework, but it looks nothing like JavaScript used in a framework.

The other language I know of with this issue is, ironically, Rust.
