I don't doubt the claim that a Java Applet can be faster than JavaScript, but I haven't ever seen a modern high-performance web application written as a Java Applet. The CAD stuff, games, etc., are always Flash (EDIT: when they aren't JavaScript). So the comparison is really Flash vs. JavaScript. And… comparing Flash to V8? I'm having trouble finding modern benchmarks, but Flash is based on ActionScript, which is related to JavaScript. JavaScript has V8, which is a world-class JIT with Google's engineering talent behind it. I'd be very surprised if Flash's JIT was competitive with V8. At least as of 2011 it wasn't [1].

My answer was in reply to "WASM enables nothing". I argue that WASM is faster than JS, therefore it enables new applications. I didn't make any claims about Java Applets or Flash performance.

  Ah sorry I thought you were replying to "no-one would complain about Flash or Java Applets". I don't disagree that WASM is faster than JS; in fact I make that point myself in several comments. My point is that WASM's speed does not enable it to be abused like Flash in a way that JavaScript cannot be, because JavaScript is already as fast as (in fact faster than) Flash thanks to modern JITs like V8. The reasons that WASM is not the "new Flash" must therefore be the same reasons that V8 + Canvas are not.

What Flash-based CAD have you seen? AutoCAD and Sketchup web versions are both using WASM. Onshape and Tinkercad use JS.

  Sorry, bad example. I have hazy memories of full-screen "creator" type apps in Flash from years ago. You are right that they are all JavaScript or WASM now (owing no doubt to the performance enhancements V8 has brought).
