How do I use props in Vue's Options API?

In Vue's Options API, you can define props in the component's options object. Here's a basic example:

export default {
  props: {
    myProp: {
      type: String,
      required: true
    }
  },
  data() {
    return {
      message: 'Hello from the component!'
    };
  }
};

You can then pass the prop from a parent component like this:

<my-component my-prop="Some value"></my-component>

What types of data can props accept?

Props can accept various data types, including String, Number, Boolean, Array, Object, and even custom types. You can specify the type in the props definition.

Can I set default values for props?

Yes, you can set default values for props by using the default property in the props definition. For example:

props: {
  myProp: {
    type: String,
    default: 'Default value'
  }
}

What happens if a required prop is not provided?

If a required prop is not provided, Vue will issue a warning in the console during development, indicating that the prop is missing.
