Create a Book constructor that has two properties :

  1. Title
  2. Author

and two methods:

  1. A method named getTitle that returns: "Title: " + the instance title.
  2. A method named getAuthor that returns: "Author: " + the instance author.

and instantiate this constructor by creating 3 new books:

  1. Pride and Prejudice - Jane Austen (PP)
  2. Hamlet - William Shakespeare (H)
  3. War and Peace - Leo Tolstoy (WP)

The name of the new object instances PP, H, and WP, respectively.

For instance, if I instantiated the following book using this Book constructor function:

  • Harry Potter - J.K. Rowling (HP)

I would get the following properties and methods:

Examples

HP.title ➞ "Harry Potter"
HP.author ➞ "J.K. Rowling"
HP.getTitle() ➞ "Title: Harry Potter"
HP.getAuthor() ➞ "Author: J.K. Rowling"

Notes

  • Read more about constructor functions in Resources.
  • Remember, after you've finished writing the constructor function, you must instantiate it through the creation of new objects.
