What is the Vue 3 Global Event Bus and how do I use it?

The Vue 3 Global Event Bus is a pattern for managing events across components. It allows you to emit and listen for events globally, making it easier to communicate between components that are not directly related.

Can you show me a simple example of how to implement it?

Sure! First, create an event bus using Vue's reactive system. Then, you can use emit to send events and on to listen for them in your components.

What are the advantages of using an event bus?

Using an event bus simplifies communication between components, reduces prop drilling, and helps manage state changes more effectively.

Are there any downsides to using the Global Event Bus?

Yes, it can lead to harder-to-track events and potential memory leaks if not managed properly. It's important to clean up listeners when components are destroyed.
