Will llrt have plans to support WebAssembly ? #493

Rust has a very fast WebAssembly runtime wasmtime, its speed is close to v8's WebAssembly

However, wasmtime will significantly increase the program size. If our program size reaches 40mb, then it seems that using v8 will be a better choice.

Hi @ahaoboy, that's true! We have no current plans supporting WASM. If we add this in the future, it will be a lightweight WASM runtime such as https://github.com/bytecodealliance/wasm-micro-runtime

WAMR is much smaller than wasmtime and is indeed more suitable for llrt.

wasmi does not support simd, which may limit some image processing libraries txiki.js may also use WAMR (I guess) https://github.com/saghul/txiki.js/issues/629#issuecomment-2244498155
