Hit the Ground Running with WebAssembly

on YouTube ↗21m

" summary

WebAssembly compiles existing C/C++/Rust code to run in the browser and at the edge, enabling concrete wins: the CDN-hosted bioasm tools power fastq.bio and deliver a 20x speedup over a JS rewrite, another app ribbon reuses ~100k lines of C and gets 2–3x runtime gains while adding file-format checks and downsampling. Browsers support Wasm for ~93% of users, SharedArrayBuffer for ~70%, runtimes include Wasmtime, Wasmer, Node and Wasm3, and SIMD in Wasm approaches near-native performance (Chrome 91 enables it).
