JavaScript Masterclass - Zero to Job-Ready with Hands-On Projects - Delete Task / 225

The video tutorial explains how to delete list items (Li) in a task management application using event listeners. It covers adding event listeners to the entire task container instead of individual delete buttons to ensure functionality for dynamically added tasks. The tutorial includes a code walkthrough for detecting clicks on delete buttons, removing parent elements, and implementing a 'clear all' feature to remove all tasks. The video concludes with a brief mention of upcoming topics like updating messages and counting elements.

Why is it beneficial to add an event listener to the entire task container instead of individual delete buttons?

• It reduces the number of event listeners needed.

• It makes the code more complex.

• It only works for static elements.

• It prevents any element from being deleted.

What is the purpose of using the event target in the delete functionality?

• To add new elements to the list.

• To identify which element was clicked.

• To change the color of the list items.

• To sort the list items alphabetically.

How does the code determine if a clicked element should trigger a delete action?

• By checking if the element has a 'delete' class.

• By checking if the element is the first in the list.

• By checking if the element is hidden.

• By checking if the element is a paragraph.

What happens when the 'Clear All' button is clicked?

• A new list item is added.

• All list items are removed.

• All list items are highlighted.

• The list is sorted in reverse order.

Which method is used to loop over and remove each list item in the 'Clear All' functionality?

• reduce()

• filter()

• forEach()

• map()

What is the next topic to be covered after implementing the delete and clear all functionalities?

• Adding new list items.

• Updating messages and implementing search.

• Changing the list item colors.

• Sorting the list items.

What approach is hinted at for managing elements in the upcoming topics?

• Using a database.

• Using counting.

• Using a third-party library.

• Using a different programming language.
