Currently, when the user clicks the Submit Book button, error messages will appear for invalid data. However, when adding valid data and clicking Submit Book again, the error messages do not clear.

At the beginning of the Submit Book button click, all error messages should be cleared out. Then only new invalid data will cause new error messages to appear.

In the example image below, a valid title was added, the Submit Book button was clicked again, but still the Title error message persisted.

In the example screenshot below, when picking October 23rd in the DatePicker, the data is being stored as October 22nd. It looks like this may be a time zone issue or parsing from a string into a Date.

On a new page, named Book.html, create an add book form. The add book form should contain input fields and validation for the following pieces of required information:

• ISBN 13 number
• Title
• Price
• Release Date

Create a class in TypeScript to hold all of this information in a single class.

• Create a documented Book class
• Create a form to add a book in HTML
• Add validation to the add book form

Using CSS, style the Add Book form, and line up the controls more consistently, such as a 2 column layout

Publish website using GitHub Pages. Add the GitHub pages URL to the main repo page and the README

Using localStorage, when a book is added by the user, it should be stored in localStorage as a string.

The user should be able to store multiple books. We need to check if there are any books currently stored in localStorage. If there are books, the newly added book needs to be stored with the existing book data. If there are no books currently stored, the new book should be stored as a list/array of size 1, so it's easy to pull the list out of storage and add to it later.

When a book is displayed on the page after filling out the add book form. It should be styled, and a layout for multiple books should be added and made responsive

When the user comes back to the website, we must read book data from localStorage. If there are some books currently being stored, we must loop through them and display them on the web page. If there are no books currently in storage, no further action is needed.
This should be completed after #9

The client-side code will be written in TypeScript for this project. We need a tsconfig.json file, options need to be decided upon. We need instructions on how to get started in a README.md file. These instructions should include:

• How to install TypeScript support
• How to compile TypeScript with the watch option

All html pages need to share a consistent header, navigation, and footer
