How can I handle errors in an event emitter?

You can handle errors in an event emitter by listening for the 'error' event and implementing a callback function.

Can you show me a code example?

Sure! Here's a simple example:

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

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

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

What if I want to handle multiple types of errors?

You can differentiate errors by checking their type or properties in the error event handler.

Is there a way to prevent the process from crashing?

Yes, by handling the 'error' event properly, you can prevent the process from crashing and manage errors gracefully.
