I want to say Rust, but for some stuff it’s probably very overkill. I love it, but there’s a reason we don’t use CPP for everything. (WASM may change things here but IDK)

Swift would be an excellent candidate for the title of “simpler Rust,” but unfortunately it’s doomed to rot in Apple’s walled garden for all eternity.

Honestly, I would say TS (which I hate, but it’s indispensable for many things) or any JVM/NET language (Kotlin, C#, both are good)
