Enter the Sandbox: JS on Wasm
summary
Shows how to run JS inside WebAssembly securely and portably by compiling small JS engines into Wasm (quickjs, Duktape, SpiderMonkey on Wasm) and moving startup work to build time with tools like wiser. Demonstrates real results: a 30% smaller bundle for a Storyblok-like app, 65% less CPU for a heavy task, ~30% faster on desktop and 60% faster on budget Android for an emulator, and production use at Fastly, Figma and PSPDFKit.
