How can I implement parent-child communication in Vue.js?

In Vue.js, you can implement parent-child communication using props and events. The parent component can pass data to the child using props, and the child can communicate back to the parent using custom events.

Can you give me an example of how to use props?

Sure! In the parent component, you can pass a prop like this: <ChildComponent :myProp='parentData' />. In the child component, you can access it using this.myProp.

What about emitting events from the child to the parent?

To emit an event from the child, you can use this.$emit('eventName', eventData). The parent can listen for this event like this: <ChildComponent @eventName='handleEvent' />.

Are there any best practices for managing state between parent and child?

Yes! It's best to keep the state in the parent and pass it down as props. This way, the parent can control the state and the child can focus on presentation.
