If you haven't already seen it, the show from a couple of years ago reflects on the issues the movie (and partially comics) had, and acts as a great sequel. Can't recommend it enough!
Hm, unfortunately nothing obvious. And your last boot ended with a crash?
Nevertheless you could try running a Memtest (this can take a while) - it will check whether any of your RAM modules are faulty: https://www.memtest.org/
That's a good approach for most cats, but some are little trash gremlins that will steal things and run away. If you have one of those cats, yarn is never safe to play with as it might rip and they could run away to eat it before you have the opportunity to take it away.
OP, do this - it's the best way to figure out what's happening. It could be any number of issues, e.g. faulty RAM. With the output of the command above people can tell you what to test for.
JS itself is great, I prefer it to most other languages due to the flexibility that it allows. Adding types through TS to safeguard against footguns doesn't mean you're not still using JS. You can also add the types using comments instead if you prefer it, which means you're actually writing raw JS.
That's your prerogative, but it honestly doesn't make sense. Typescript adds almost no functionality to JS (and the few pieces it adds are now considered mistakes that shouldn't be used anymore). It only focuses on adding typing information, and in the future you'll be able to run TS that doesn't use those few added features as JS (see the proposal).
You can also add the TS types as comments in your JS code, which IMO shows that it's not a different language.
