Why Should You Consider JavaScript on WebAssembly?
summary
WebAssembly lets JavaScript run where a native JS runtime is unavailable by compiling an engine and bytecode into a module; Javy compiles JavaScript into a WASM module and produces a pre-initialized snapshot so startup cost drops. Shopify uses this for synchronous, sandboxed extensibility — Shopify Functions run as sandboxed WASM — and the demo shows a simple index.wasm executing “hello world.” Multi-language hosts (worker server) interoperate and a standalone Python interpreter fits at ~18 MB as a WASM binary.
