How can I handle errors in EventEmitter?

How can I handle errors in EventEmitter?

You can handle errors in EventEmitter by listening for the 'error' event. Here's a simple example:

const EventEmitter = require('events');
const myEmitter = new EventEmitter();

myEmitter.on('error', (err) => {
  console.error('An error occurred:', err);
});

myEmitter.emit('error', new Error('Something went wrong!'));

What happens if I don't handle the error event?

If you don't handle the 'error' event, the Node.js process will throw an unhandled error and terminate.

Can I use try-catch with EventEmitter?

You can't use try-catch directly with EventEmitter events, but you can wrap the code that emits events in a try-catch block.

Are there best practices for error handling in EventEmitter?

Yes, some best practices include always listening for the 'error' event, logging errors, and using custom error classes.
