The biggest weakness of WASM IMO is that it doesn't have its own standard library. It relies on the HTML DOM. This is an awkward, overcomplicated API that tends to differ between browsers, and worst of all, changes all the time. Because of this, WASM will likely remain a second-class citizen in the browser. It will also keep suffering of the problem of code constantly breaking when the DOM changes.
