How do I emit events in Vue 3?

In Vue 3, you can emit events using the emit function. You typically do this in a child component to communicate with the parent.

Can you show me a code example?

Sure! In your child component, you can do something like this:

this.$emit('myEvent', data);

And in the parent component, you listen for the event like this:

<ChildComponent @myEvent="handleMyEvent" />

What if I want to pass multiple arguments?

You can pass multiple arguments by including them in an array:

this.$emit('myEvent', arg1, arg2);

Then, in the parent, you can access them in the event handler.

Is there a limit to the number of events I can emit?

No, there's no strict limit to the number of events you can emit. Just ensure that your event names are unique to avoid conflicts.
