When I checked the code in index.html at https://validator.w3.org/, it indicated some errors.

In terms of input validation,
- Are all input properly checked?
- Can
.valuebenull? (Do we need to checksomeInputElement.value == null?) - What if a user enters only space characters in the "title" input field?
- What if a users enters
-1or3.1416in the "pages" input field?
With the way the book's title is assigned to an HTML element, a book with a title containing special character sequence such as <i> can possibly ruin the display.

Instead of deleting the table rows one by one, can you think of a more efficient way to remove all rows (except the <th>...</th>) in the table?

At the moment when the alert message is displayed, has the book mentioned in the message been deleted yet?
How would you rearrange these statements to make the message truthful?
