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

The Vue Event Bus is a simple way to communicate between components in Vue.js. It allows you to emit and listen for events.

Can you show me a basic example of how to set it up?

Sure! First, create a new Vue instance as your event bus. Then, in your components, you can use this.$bus.$emit('eventName') to emit an event and this.$bus.$on('eventName', callback) to listen for it.

What are the advantages of using the Event Bus?

The Event Bus simplifies communication between components, especially in larger applications, and helps avoid prop drilling.

Are there any downsides to using the Event Bus?

Yes, it can lead to harder-to-track bugs if not managed properly, as events can be emitted from anywhere.
