- 13. No standard / No best practice Catch everything Node.js handles asynchronous I/O requests with a non-blocking, single-threaded event loop. It is particularly well-suited to distributed systems that make a lot of network requests.
- 15. Memory Leak - Heapdump + Chrome Developer Tools - Force Garbage Collection node --expose-gc app.js -> global.gc() V8 Memory Limit - node --max-old-space-size=16000 app.js pm2 start bin/www –node-args=“--max-old-space- size=16000 ” V8 Engine
