What is the difference between emit and props in Vue 3 with TypeScript?
In Vue 3, props are used to pass data from a parent component to a child component, while emit is used to send events from a child component back to the parent.
Can you give me an example of how to use emit in a Vue 3 component?
Sure! In a child component, you can use this.$emit('eventName', payload) to emit an event. The parent component can listen for this event using @eventName='handlerMethod'.
How do I define types for props in TypeScript?
You can define types for props in TypeScript by using the defineProps function or by declaring a props object with TypeScript interfaces.
Is it possible to use both emit and props together?
Yes, you can use both emit and props together in a component. Props can pass data down, while emit can send events back up.
