Well, TS transpiles to JS which then runs on Node, aka V8, a native JIT compiler. So yes, I guess?

Kind of, given that V8 performance is never going to be as good as AOT compiled language, and JIT needs warmup time.

It is no accident that famous JavaScript tools keep being rewritten into C++, Dart, Go and Rust.
