Web Assembly, the Future of JS, and a multi-language web
summary
ImageMagick compiled to WebAssembly runs an in-browser photo editor fully offline, manipulating pixels client-side with a claimed ">100× speed vs JS" for common filters and exporting PNGs. The same precompiled wasm module runs unchanged on a Raspberry Pi 3 runnable, demonstrating cross-architecture binaries without recompilation. WebAssembly targets languages like Rust, C and Go and achieves broad reach with 91.78% browser support. Cloudflare Workers is mentioned as a wasm-capable edge option with a free tier of 23 functions / 100,000 calls per day.
