React - Use PropTypes to Define the Props You Expect

Tell us what’s happening:
Describe your issue in detail here.

Your code so far

import PropTypes from 'prop-types';

const Items = (props) => {
  return <h1>Current Quantity of Items in Cart: {props.quantity}</h1>
};

// Change code below this line
Items.defaultProps = {
  quantity: 0
};
Items.propTypes = {
  quantity: PropTypes.number.isRequired
};
    ShoppingCart.defaultProps = {
  quantity: 0
}
// Change code above this line



class ShoppingCart extends React.Component {
  constructor(props) {
    super(props);
  }
  render() {
    return {Items}  }
};

Link to the challenge:

You were not asked to add defaultProps for the ShoppingCart component, but if you want to do that it has to go below (after) the component.
