- Class and Constructor Creation
- Book Class
- Create a script called library.js. In this file create a constructor function for a Book object. The Book object should have the following properties:
- Title
- Available: Boolean representing whether the book is checked out or not. The initial value should be false.
- Publication Date: Use a date object
- Checkout Date: Use a date object
- Call Number: Make one up
- Authors: Should be an array of Author objects
- Author Class
- Create a constructor function for an object called Author. It should have a property for the first name and last name of the author.
- Patron Class
- Create a constructor function for an object called Patron. This represents a person who is allowed to check out books from the library.
- Give it the following properties:
- Firstname
- Lastname
- Library Card Number (Make one up)
- Books Out: Make it an array
- fine: Starts a 0.00
- B. Methods to add
- Book Class
- Add a function to the Book prototype called "checkOut". The function will change the available property of the book from true to false and set the checkout date. The
- checkout date should be set to the current date minus some random number of days.
- Add a function to the Book prototype called "checkIn". The function will change the available property of the book from false to true.
- Add a function called isOverdue that checks the current date and the checked out date and if it's greater than 14 days it returns true
- Patron Class
- Add a function to the Patron prototype called "read" that adds a book to it's books out property.
- Add a function to the Patron prototype called "return" that removes a book from it's books out property.
- C. Test Program
- Create 5 different books from the Book Class and store them in an array called catalog.
- Create 5 different patrons from the Patron Class and store them in an array called patrons.
- Write a loop that simulates checkouts and checkins for a 3 month period. Every day iterate over the catalog, and every person in the patrons array. If the patron
- currently has the book checked out then check it in. If it is not checked out then add it to the patrons list of books via the patrons read method. If the book is overdue
- then add a fine of $5.00 to the patron returning it. At the end of the 3 month period, display each patron, the books they have currently checked out and any fine they
- may have.
