I see you mentioned JS, but not TS. If you haven’t tried TypeScript, you 100% should! It helps a lot at scale.
Also, I really do recommend Rust. It’s pretty awesome having the errors actually make sense, and it’s not as complicated as the hype makes it out to be (until you get into async rust lol).
As others have mentioned, C# is also awesome.
I feel like we hear this every single time though. “Largest tech leap in a hardware generation” very much means “we’ll bump the graphics a little, we’re still targeting 30fps though”
