Node.js · Senior · Question 49 of 75

Why is `uncaughtException` + 'log and continue' a bad pattern?

✓Correct answer: After an unexpected throw, state may be corrupted (half-done updates, leaked resources); the safe path is log, stop accepting work and restart
2Logging inside uncaughtException is impossible
3It makes the process exit twice

Explanation

Use the handler only for synchronous cleanup and logging, then exit with a non-zero code and let the orchestrator restart the process.
