Re:How JavaScript works: inside the V8 engine by Fifer82 on Monday August 21, 2017 @12:48PM (#15065833)
I really don't know much about wasm.

I just wondered though, from a birds eye view, does using wasm effectively give you control of everything within the "frame" of your browser?

Can I get rid of the DOM(boilerplate aside), get rid of CSS?

For example HTMLCanvasElement is a flat surface. I can do what I want within it as a scene graph renderer.

Could I do that with wasm? Could I invent my own 2D entities (x, y, width, height). My own 2D Constraints resize like Apple Devices etc?

It's still in the same sandbox as JavaScript. You don't get any new API's. There's only going to be speedup on CPU-intensive things.
