We have learned Object-Oriented Programming and how class and inheritance work in JavaScript. Now, let's apply all of the concepts we have just learned and build an OOP based approach to the book store with a lot of books in it.

You will be working in the solution.js file and the tests you can reference are in the solution.test.js file. To check on your progress and if you are passing the tests, you can click on the "Run Tests" button. To submit your work, you should click on the "Submit" button. You will be asked to review your test and make a final submission. After you are done with the final submission, you can't resubmit afterward.

• Create two classes, one for the Bookstore and another for each Book. Hint: These two classes are not extending each other, they are just 2 separate classes.

• Bookstore class

  • Should receive a name to it's name property.
  • Should have books property to store the books.

• Book class

  • Should receive a name and the quantity.
  • Should have a name and quantity property.

The Bookstore class should have methods for:

1. Pick a book: pickBook method

   • Should receive a book name.
   • Should check if it exists, and if not, it should return the message: "Book not found".
   • Should check if the book is available due to the quantity of the books, and if there are no books available (quantity property equals 0), it should return the message: "Not available". If the book exists and it's available then subtract one book from the book quantity and return the book.

2. Store a book: storeBook method

   • Should receive a book and add it to the books property.

3. Show books: showBooks method

   • Should show every book on the console.

The Book class just needs a method to change the book name:

1. Change the name: changeName method -

   • Should receive a new book name and set the name property to it.

Good luck!
