Why WebAssembly is Changing the Game
What is WebAssembly?
WebAssembly (WASM) is an open standard for executable code in web browsers. It provides a portable target for compiling programming languages, enabling performance capabilities beyond traditional web technologies. Unlike JavaScript, WebAssembly executes at native speed, making it ideal for CPU-intensive tasks.
Performance Benefits
- Runs at near-native speed using virtual machines
- Memory-safe with sandboxed execution
- Can be compiled from C/C++/Rust
- Interoperates seamlessly with JavaScript
Use Cases
Image/Video Processing
Complex media manipulation tasks perform 10x faster in WebAssembly
3D Rendering
Real-time 3D graphics for games and simulations
Legacy Code
Port older applications to web platforms
Cross Platform Tools
Create tools that run identically across browsers
