I wouldn't say the source language is not meaningful. If you wrote an ahead-of-time JavaScript-to-WebAssembly compiler and benchmarked the WASM generated by that, it would probably be a lot slower than the WASM generated by the Rust compiler, no?

Has anyone compiled v8 to WASM so we can finally run JS in the browser? ;)

[hunterb123]

v8 is a JIT engine, WASM would not support it.

JavaScriptCore has been compiled to WASM though:

People usually ask why, the answer is usually for fun or for sandboxed plugins.

I imagine that, if one were feeling extremely masochistic, one could generate WASM, JIT-style, and load it as needed. The result may not perform well.

[throwaway894345]

I assumed the JIT would emit WASM.

please don’t give them more ideas
