I disagree TypeScript is good enough.

It's easy to run into untyped (or partially typed) dependencies (a massive pain to write) or in internal code which uses any/unknown somewhere (causing typing holes which allow for whatever inputs).

I love types but I can't trust TypeScript types to be valid, I've been bit too many times.

Rust (or any other really typed language) would be great if the solutions are mature enough. It's not just for memory control.
