How can I handle errors when using emit in Vue 3?

In Vue 3, you can handle errors emitted from child components by using the v-on directive with a custom error handler.

Can you show me an example of that?

Sure! You can define a method in your parent component that handles the error and pass it to the child component like this:

<ChildComponent @error="handleError" />

And in your handleError method, you can log the error or display a message.

What if I want to catch errors in the child component itself?

You can use a try-catch block within your child component's methods to catch errors and then emit an error event to the parent.
