Here, "the problem" is that parsing JavaScript is very slow (and the second problem is that sending these files can be pretty slow, too). WebAssembly cannot really ship JavaScript code. Well, I guess it could if someone were to write a JavaScript to native compiler and ship it as WebAssembly, but then you would end up with more problems: - yet another JavaScript target, with possible incompatibilities, security issues, etc; - you still need to ship the binaries, which will most likely be much larger (and much slower to parse) than your initial source code; - "interesting" interactions between Wasm-compiled JS and browser-compiled JS, as well as the DOM, garbage-collection, ...
