Image processing, simulations, on-device models: heavy compute in the browser was long slow or simply impossible. WebAssembly has pushed that line from experimental to production-viable.
Near-native speed, in a tab
Code from Rust, C++ or Go now runs at near-native performance alongside your JavaScript. For the right tasks — not everything — that opens doors that used to be native-only.
Our take
It's not a replacement for JavaScript, but a sharp tool for specific problems. We reach for it when the compute load justifies it, not by default.
