Error Handling in Async Code

What Node.js error handling pattern is shown?

process.on('uncaughtException', (error) => {
  logger.fatal(error);
  // Perform cleanup
  process.exit(1);
});

process.on('unhandledRejection', (reason, promise) => {
  logger.error('Unhandled Rejection at:', promise, 'reason:', reason);
  // Optionally crash on unhandled rejections
  throw reason;
});

Basic error logging
Global error handlers
This shows Node.js global error handlers: 1) Catches both synchronous and asynchronous unhandled errors, 2) Provides last-resort error handling, 3) Enables proper logging before crash, 4) Allows cleanup before process exit, 5) Critical for preventing silent failures in production, 6) Best practice for Node.js applications.
