This is not what GP asked for. That's the most requested feature from the state of JS survey. I bet the percentage of web developers who want this are a tiny minority. There are just too many issues with this. Static typing without the benefits of better runtime performance, soundness, strong typing etc. is basically just documentation/comments with extra steps. Also TS is a complex, moving target. Most devs don't want to learn new fancy features every couple of months, but prefer stability guarantees. Several notable projects have moved away from TS. Even Ryan Dahl admitted that integrating Deno with TS was probably a mistake. Meanwhile you have WASM slowly and steadily getting crucial features on a sound foundation. I'm extremely cautious about TS and wary of the hype surrounding it.
