Challenge: React - Use PropTypes to Define the Props You Expect

Link to the challenge:

Define propTypes for the Items component to require quantity as a prop and verify that it is of type number .

For this challenge, you should only modify code between the commented lines. You have done this, but you have also added other lines of code which are not required here (as this is taken care of for you behind the scenes).

If you remove import and require statements at the top, and the ReactDOM.render at the bottom, your code will pass.
