Use PropTypes to Define the Props You Expect Issue

JavaScript
1

Tell us what’s happening:
This code isn’t passing the test.
The tests are insisting that The Items component should include a propTypes check that requires quantity to be a number.
BUT I HAVE SUCH A CHECK!!!
Any and all help will be appreciated.
Your code so far


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

// change code below this line
Items.propTypes = {
  quantity: PropTypes.number,
};
// change code above this line

Items.defaultProps = {
  quantity: 0
};

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

Currently, you have specified that quantity is a number, but you have not required the quantity prop.
