What makes WebAssembly fast?

Re:What makes WebAssembly fast? by ZenPsycho on Wednesday March 01, 2017 @01:08AM (#13761615)

browsers that support WASM will support ES6 natively. compiling ES6 to WASM would not be a good idea, since you would have to send a garbage collector and full dynamic language runtime down the pipe instead of just using the one in the browser.

wouldn't you rather just run ES6 right in the browser instead of compiling it first at all?

If all major browsers support 100% of the spec and every implementation is bug to bug compatible with the others, yes, I would rather run ES6 directly in the browser. The problem is fragmentation and not supporting the whole spec -- some functions working in Firefox and Chrome and not implemented in IE/Edge or Safari.

Has any runtime anywhere had 100% compatibility with anything ever?
