Delete Book from List

The video tutorial covers how to implement a delete functionality for books in a UI using event delegation. It explains setting up event listeners, targeting elements for deletion, and removing them from the DOM. The tutorial also includes testing and debugging the functionality. Finally, it introduces the concept of refactoring the code using ES6 classes for better structure and organization.

Why is event delegation necessary when dealing with dynamically added elements?

• It prevents any events from being triggered.

• It makes the UI more complex.

• It increases the page load time.

• It reduces the number of event listeners needed.

What is the purpose of the 'preventDefault' method in an event listener?

• To add a new event listener.

• To log the event details to the console.

• To prevent the default action of the event.

• To stop the event from propagating.

Which DOM element is targeted for deletion in the prototype method?

• The A tag.

• The TR element.

• The entire table.

• The TD element.

What is the role of the 'UI.prototype.deleteBook' method?

• To show an alert message.

• To delete a book from the UI.

• To clear all fields in the form.

• To add a new book to the list.

What message is displayed when a book is successfully removed?

• Book added.

• Book removed.

• Error occurred.

• Operation successful.

What is the next step after implementing the current functionality?

• Removing all event listeners.

• Implementing ES6 classes.

• Adding more books.

• Changing the UI design.

Which of the following is NOT part of the UI prototype?

• Create new book.

• Add book to list.

• Delete book.

• Clear fields.
