• Create a basic HTML form.
• Modify the form so if the user submits the form with a blank input the page turns red.
• Create a register which records every valid input from the form.
• Create an object prototype for books with the following properties:

• Name
• Date created
• Count

• Updating the form should increment the count for the instance of that book.
• Extend the book prototype with an encyclopedia prototype. In addition to the properties a book has, an encyclopedia has a year property. (The year can default to being the current year.)
• Create a mechanism to distinguish book and encyclopedia input.
• Add a new element to the page. Append user input from the form to that element, only if the input is an encyclopedia.
• Display encyclopedias in alphabetical order.
