Node.js - Error Handling Patterns

Given this code snippet, what will be the output when an uncaught exception occurs? const http = require('http'); const server = http.createServer((req, res) => { throw new Error('Oops'); }); process.on('uncaughtException', (err) => { console.log('Error caught:', err.message); process.exit(1); }); server.listen(3000); // A request is made to the server

ALogs 'Error caught: Oops' but server keeps running

BServer crashes without logging anything

CLogs 'Error caught: Oops' and exits with code 1

DNo output, server ignores the error

Step-by-Step Solution

Solution:

Step 1: Understand uncaughtException handler
The handler logs the error message and calls process.exit(1) to stop the app.
Step 2: Analyze behavior on thrown error
The thrown error triggers the handler, so it logs and exits with code 1.
Final Answer:
Logs 'Error caught: Oops' and exits with code 1 -> Option C
Quick Check:
Uncaught exception logs and exits [OK]

Quick Trick: Uncaught exceptions trigger handler then exit if called [OK]

Common Mistakes:

Thinking server keeps running after exit
Expecting no logs
Confusing error handling with ignoring errors
