Learn EMSCRIPTEN with Real Code Examples

WebAssembly runs at near-native speed in modern browsers

asm.js fallback is slower but widely compatible

Threading requires SharedArrayBuffer support

Memory usage can impact performance in large applications

Inlining and optimization flags improve runtime speed

Code runs in browser sandbox, preventing access to OS resources

Beware of cross-site scripting (XSS) when interacting with DOM

Validate inputs and handle exceptions to prevent crashes

Use HTTPS for loading Wasm modules

Avoid exposing sensitive logic directly in Wasm without protection

Browser console logs for runtime debugging

Use performance API to measure execution time

Monitor memory and thread usage

Check module loading and instantiation time

Integrate with JS logging or analytics frameworks

Ensure memory safety in C/C++ code

Use Emscripten optimization flags for performance

Test cross-browser compatibility

Keep JavaScript glue clean and modular

Profile and debug using browser dev tools
