Several tools can assist in diagnosing these errors. For 'unhandled error events', debuggers (like those in VS Code, Chrome DevTools) and logging libraries are invaluable. For 'error connect etimedout', network monitoring tools (e.g., Wireshark, tcpdump) can analyze network traffic and identify latency issues. Application Performance Monitoring (APM) tools (e.g., New Relic, Datadog) provide insights into application performance and error rates. Node.js's built-in inspector can also be useful.
