8,130 PointsWhy there's no change in dueDate, book and currentBook properties?
I have written some code and I saw that some properties aren't changing.
But well... In code that we get from Ahley, properties also aren't changing. Take a look at console log... At Book's dueDate and patron properties and Patron's currentBook property after checkOut(). There's still 'null' value. Why is that?

Try logging out the specific property you want to see changing, for example:
patron.checkOut ( book );
console.log ( book.patron ); // log the specific property to see it set
patron.returnBook ( book );
console.log ( book.patron ); // and now cleared again
