I guess this site should be sent to anybody saying javascript should be blocked in web browsers... In the end whether a technology is used to track and exploit or educate and delight is entirely up to us.
Aren't most things neatly placed in <canvas> tags? Not to mention that it's basically all some form of web GL, which could avoid JS pretty easily is it wanted to these days.
What we want blocked isn't all of javascript, it's some of the browser APIs.
You definitely can’t use canvas (or any DOM API) without JS. The idea of using WebAssembly for WebGL (or canvas via whatever JS bridge) almost certainly won’t satisfy a large portion of the no-JS crowd, whose opposition to JS is opposition to the browser as an application platform generally.
The "no js" crowd isn't about language wars rather client side programmability. As such WASM is only a superset for this conversation, not an alternative.
