Vampire Survivors. I was pretty surprised when I looked at the game files

There is actually a decently popular game made in Electron that just recently switched to Unity. RIP

A quick search showed me that’s mainly for AI, or can it be used for general scripting too?

I get why JavaScript can be terrible but at least there’s TypeScript. I’d argue Python suffers from the same problems but hasn’t got anything comparable to TS for keeping types in check and can’t autoformat well because whitespace is syntactically meaningful. In that way I think Python is worse to write maintainable code with.
