How do I validate props in Vue.js?

In Vue.js, you can validate props by defining the 'props' option in your component. You can specify types, required fields, and default values.

Can you give me an example of prop validation?

Sure! Here's an example:

props: {
  name: {
    type: String,
    required: true
  },
  age: {
    type: Number,
    default: 18
  }
}

What happens if a prop validation fails?

If a prop validation fails, Vue will issue a warning in the console during development, but it won't stop the application from running.

Can I use custom validation for props?

Yes, you can use a custom validator function in the prop definition to implement more complex validation logic.
