What are the best practices for using emit in Vue 3?

In Vue 3, it's best to use emit for communication between components. Always use a consistent naming convention, like 'update:modelValue' for v-model.

Can you give me an example of how to use emit with a custom event?

Sure! You can emit a custom event like this: this.$emit('customEvent', payload); and listen for it in the parent component.

Should I use emit for all component communication?

Not necessarily. Use emit for parent-child communication. For sibling components, consider using a shared state or event bus.

What about TypeScript support for emit?

In TypeScript, you can define event types in your component's emits option to ensure type safety when using emit.
