JavaScript is great, but it wasn’t built for high-performance tasks like complex data processing or 3D rendering. That’s where WebAssembly (WASM) comes in — a technology that can deliver near-native performance directly in the browser. In this talk, I'll show you how WASM can supercharge your web apps with a real-world demo, where it dramatically outperforms JavaScript in sorting a large dataset. You'll also discover how industry leaders like Prime Video and Figma leverage WASM for massive performance gains. This session will equip you with practical insights and best practices to integrate WASM into your own projects.
