Run high-performance code in the browser.
Use WebAssembly for computationally intensive tasks.
What is WebAssembly?
Binary instruction format for web browsers
Near-native performance
Language-agnostic
Rust to Wasm
// Rust code
#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
a + b
}
// Build
cargo build –target wasm32-unknown-unknown
JavaScript Usage
import init, { add } from ‘./pkg/my_module.js’;
await init();
console.log(add(1, 2)); // 3
Use Cases
✅ Image/video processing
✅ Game engines
✅ Scientific computing
✅ Encryption
Conclusion
WebAssembly unlocks browser performance limits!
