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

Items.defaultProps = {
  {quantity: 10}
}
class ShoppingCart extends React.Component {
  constructor(props) {
    super(props);
  }
  render() {
    { /* change code below this line */ }
    return <Items />
    { /* change code above this line */ }
  }
};
