Object as PropType

In React, PropTypes are used to validate the data types of props passed to a component. An Object as a PropType means that the prop being passed to the component should be an object.
For example, consider a component that has a prop called "user" that should be an object containing the user's name and email. Here's how we can define the PropTypes for this component:
```
import PropTypes from 'prop-types';
function UserComponent({ user }) {
return (
<div>
<h2>{user.name}</h2>
<p>{user.email}</p>
</div>
);
}
UserComponent.propTypes = {
user: PropTypes.shape({
name: PropTypes.string.isRequired,
email: PropTypes.string.isRequired
}).isRequired
};
```
In the above example, we are using the `PropTypes.shape` validator to ensure that the `user` prop is an object that contains the `name` and `email` properties, both of which should be strings. The `.isRequired` modifier ensures that the prop is required and must be passed to the component.
