> js seems to already have a bytecode for their JIT runtime This is kind of a nonsensical statement. JS itself doesn't have a bytecode, it's just a specification of the language you write scripts in. Each implementation has its own intermediate representations, including bytecode formats. WASM is a vendor-neutral standard that is designed as a compilation target and designed with safety in mind. SpiderMonkey/JSC/V8 internal bytecode formats are just that, compiler internals. |
