This isn’t about replacing javascript, this compiles something that looks a bit like Python to C and then to WASM. Which browsers can run natively these days. But you can do that with any source language if there’s a compiler for it, type safe or not. You can compile Rust to WASM too for example. So nothing’s getting replaced, these are just additional tools for Web developers.
Dunno when you played it but they’ve added tons of shit in the past years, so it might be worth it to give it another chance.
