Extending JavaScript with Rust

on YouTube ↗22m

" summary

Shows concrete results: Rust modules compile to WebAssembly and swap into existing JS apps via wasm-pack and bindings, replacing hot code paths. Firefox devtools parsing becomes 6× faster (with tweaks up to ~11×). A WordPress Gutenberg parser rewritten in 313 Rust lines runs a median 98× faster (2.5s → 25ms). Demonstrates an Advent of Code example, npm packaging the wasm module, and that the replacement works transparently in the web app.
