How can I use EventEmitter in my React application?

How can I use EventEmitter in my React application?

You can use the EventEmitter class from the 'events' module in Node.js. First, install it using npm.

Can you show me a simple example?

Sure! First, create an instance of EventEmitter. Then, you can define events and listeners like this:

import EventEmitter from 'events';

const eventEmitter = new EventEmitter();

eventEmitter.on('eventName', () => {
  console.log('Event triggered!');
});

eventEmitter.emit('eventName');

How do I integrate this with a React component?

You can integrate it by creating the EventEmitter instance in your component and using it in lifecycle methods or hooks.

What if I want to clean up the listeners?

You can remove listeners in the useEffect cleanup function to prevent memory leaks. Use eventEmitter.off('eventName', listener).
