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 bindings.
Can you give me an example of how to use emit?
Sure! If you have a child component that needs to notify the parent, you can emit an event like this: this.$emit('eventName', payload);
.
What should I avoid when using emit?
Avoid emitting too many events or using vague names. This can lead to confusion and make your code harder to maintain.
Is there a limit to how many events I can emit?
There's no strict limit, but it's best to keep the number of events manageable to maintain clarity in your component communication.
