WebAssembly vs JavaScript: Which Is Faster?

on YouTube ↗32m

" summary

Compares WebAssembly and JavaScript performance by compiling Rust/C/C++ to wasm and running numeric, crypto, image-codec and real web workloads against JS engines. Finds WebAssembly gives faster raw numeric performance and benefits from streaming compilation and binary loading, but cross-language calls into JS are costly; fully native wasm combined with parallel workers yields the best results for image-processing pipelines.
