Can we use EventEmitter in React?

First, you’ll need to create two components, one parent and one child. Next, you’ll import the child component in the parent component and return it. Then you’ll create a function and a button to trigger that function. Also, you’ll create a state using the useState Hook to manage the data.

Subscribe to events in componentDidMount(), unsubscribe in componentWillUnmount(), and call setState() when you receive an event.
