> Even native performance is not nearly enough and you need to employ algorithms that use 256- and 512-bit vector operations. At that point, we are talking about running natively on the CPU, and for that you need something that isn't just a web app. Yes, as the article said - this is what WebAssembly is for. Shell : Executable :: Javascript : WebAssembly. WebAssembly supports wide SIMD instructions (https://v8.dev/features/simd https://v8.dev/features/simd) and many WebAssembly runtimes pre-compile the web assembly to native machine code (eg https://crates.io/crates/wasmer-compiler-llvm https://crates.io/crates/wasmer-compiler-llvm). In a way, you could think of WebAssembly like a more portable LLVM bitcode - it’s a compact, partially optimized representation of a program ready for an optimizing machine-specific compiler to lower to the native architecture. But, it’s also possible to interpret it in contexts that prefer fast start up.
