Modern JavaScript from the Beginning - Second Edition - Update Item and Reset State

The video tutorial explains how to implement an edit mode in a JavaScript application. It covers the logic for switching to edit mode, removing items from local storage and the DOM, and resetting the UI after editing. The tutorial also addresses preventing duplicate entries in the list. The instructor demonstrates these concepts with practical examples, ensuring the app functions correctly by updating items without duplication.

What happens when you click an item in edit mode?
