What I'm asking really is what is the benefit of TS if we could use decent and improving coding AIs to help us code in Rust, even if we are new to it, or never used it, and compile to WASM. Much faster execution per my experience. I mean not even comparable.
It's nice for performance, but if that's not a bottleneck, Typescript is pretty convenient. It has better tooling for the web, and compiles almost instantly. Rust -> WASM can be frustratingly slow if you're exploring a new idea or prototyping.
