What are the differences between emit and event bus in Vue 3?

In Vue 3, emit is used for parent-child communication, while an event bus is for sibling or non-related components.

Can you give me an example of using emit?

Sure! In a child component, you can use this.$emit('eventName', data) to send data to the parent.

And how would I set up an event bus?

You can create a new Vue instance as an event bus and use it to emit and listen for events across components.

Which method is better for larger applications?

For larger applications, using Vuex for state management is often recommended over an event bus for better scalability.
