How can I use EventEmitter in Node.js for advanced scenarios?

You can use EventEmitter to handle complex event-driven architectures, like managing multiple listeners and custom events.

Can you give me an example of using EventEmitter with multiple listeners?

Sure! You can create an EventEmitter instance, add multiple listeners for the same event, and emit the event to see all listeners in action.

What about error handling with EventEmitter?

You can listen for the 'error' event specifically, and handle errors gracefully by providing a listener for it.

Are there any performance considerations I should be aware of?

Yes, having too many listeners can lead to memory leaks. It's important to manage listeners properly, especially in long-running applications.
