Turbocharged Javascript with hand crafted WASM
summary
Shows that handcrafted WASM can replace hot JavaScript paths by compiling tiny binaries, embedding them via Base64 and calling exported functions from JS. Uses wabt / wat→wasm tooling and browser WebAssembly APIs; demos include interactive canvas particle systems rendering thousands to millions of particles with near-zero GC jitter and a Conway’s Game of Life implemented in about ~140 bytes of wasm, demonstrating dramatic size and performance wins for CPU‑heavy work.
