Best Practices
Prevention:
✓ Clear references when done
✓ Remove event listeners
✓ Clear timers and intervals
✓ Use WeakMap/WeakSet for caches
Monitoring:
✓ Track memory usage over time
✓ Set up alerts for high usage
✓ Take periodic heap snapshots
✓ Monitor GC frequency
Optimization:
✓ Use streams for large data
✓ Pool frequently created objects
✓ Avoid closures capturing large data
✓ Process data in chunks
Conclusion
Node.js memory management relies on V8's garbage collector. Prevent leaks by cleaning up references, use streams for large data, and monitor memory usage in production. Regular heap snapshots help identify leaks before they cause issues.
