How do I use prop types in Vue?

How do I use prop types in Vue?

In Vue, you can define prop types in your component by using the props option. You can specify the type of each prop, whether it's required, and provide default values.

Can you give me an example of defining props?

Sure! Here's a simple example:

export default {
  props: {
    title: {
      type: String,
      required: true
    },
    likes: {
      type: Number,
      default: 0
    }
  }
}

What happens if I pass the wrong type?

If you pass a prop of the wrong type, Vue will issue a warning in the console during development, but it won't stop your app from running.

Can I use custom validators for props?

Yes, you can define custom validators by providing a function that checks the prop value and returns true or false.
