Rust WebAssembly: Building High-Performance Web Applications

Last year I ported an image processing pipeline from JavaScript to Rust compiled to WebAssembly. The JS version took 1.2 seconds to apply a chain of filters — blur, sharpen, color correction, resize — to a 4K image in the browser. The Rust Wasm version did the same work in 58 milliseconds. Not a typo. A 20x speedup, running in the same browser, on the same machine, called from the same React app.
