Why 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?

You're probably examining live references in the dev tools, and the states have already changed back before you can examine them.

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
