useEventEmitter

Sometimes it is difficult to pass events between multiple components. By using EventEmitter, this can be simplified.

To get an instance of EventEmitter, you can call useEventEmitter in React components.

If the component renders multiple times, the return value of useEventEmitter in every render process will stay unchanged and no extra EventEmitter instance will be created.

You can also create instances of the global sharing.
