WebAssembly as a lower level abstraction is going to make web dev very interesting once the tech finally pays off, but it's been almost 10 years since it was announced and there's still no viable alternative to javascript to come out of it.

It would have been nice if a cleaner, stricter and more "designed" alternative with full access to browser features had emerged in the meantime. I'd even accept Dart if it had managed to get broad browser support.

Instead we're in a waiting game where we're all forced to use Javascript for any real work until the horizon is crossed and we can finally use a dozen of wasm-targeted languages.
