What are some examples of using emit in Vue 3?

Can you explain how to use emit in Vue 3?

Sure! In Vue 3, emit is used to send events from a child component to its parent. You can use it to communicate changes or actions.

Can you give me a simple example?

Absolutely! Let's say you have a child component called Child.vue. You can emit an event like this: this.$emit('myEvent', data); in the child, and listen for it in the parent with @myEvent='handleMyEvent'.

What kind of data can I send with emit?

You can send any type of data, such as strings, numbers, objects, or arrays. Just pass it as the second argument in the emit method.

Are there any best practices for using emit?

Yes! It's best to keep your event names clear and descriptive, and to limit the number of events emitted to avoid confusion.
