How do I use emit and listen in Vue.js?

In Vue.js, emit is used to send events from a child component to a parent component, while listen is used to handle those events in the parent.

Can you give me an example of how to implement this?

Sure! In the child component, you can use this.$emit('eventName', data) to emit an event. In the parent, you can listen for it using @eventName='methodName'.

What if I want to pass multiple parameters?

You can pass multiple parameters by including them in the data object when you emit the event, like this: this.$emit('eventName', param1, param2).

Is there a way to handle emitted events in a centralized way?

Yes, you can use a global event bus or Vuex for centralized event handling, which is useful for larger applications.
