I'm both excited and terribly disappointed.

I feel like webdev ecosystem after the fall of Flash took a wrong turn and missed a huge opportunity. For whatever reason people opted for both sticking with JS and backward compatibility. I can clearly see an alternative universe where you have a browser that accepts both a <script> with JS and another, modern language, and it's up to the developer to chose if he wants to transpile/recompile the code for backward compatibility or go all in for new features.

I mean Typescript is cool, but it's reinventing the wheel, we already had that with ES4 over 15 years ago and WASM is still a second class citizen for hackers.
