Honestly I don't hate the language itself that much (I'm just learning it though so who knows) but developing with it fucking sucks. First npm installs a thousand dependencies, then you have to use it to install an entirely different package manager (yarn) and hope it works.
If you're using npm, you install a package or two that you're working with and get 10+ vulnerabilities. It tells you to run "npm audit fix" so you do it, but it just lists the vulnerabilities again and tells you to run "npm audit fix", so apparently you're just stuck with those.
Then you try running your react app and it crashes with an error about failing to stat a random file in your home directory. It turns out that you mistyped an import, and instead of giving an error about that it recursively backs up and checks every single file to see if it's the one it's looking for. Cool.
That's will never happen though. It isn't flexible enough so there will always be some kind of VM added to stuff like that. People want to be able to create programs that can be run easier than downloading and installing one to a computer (which has no sandboxing whatsoever). Better to just start off with something simple than tack it on. It's still possible to have plenty of functionality without being able to do very good fingerprinting.
