Post Edit State & Update [1]

The video tutorial covers the implementation of an update feature in a CRUD application using JavaScript. It begins with an overview of the CRUD application and the need for an update function. The tutorial then guides through setting up an event listener for the edit state, implementing the enable edit function with event delegation, and retrieving post information using DOM traversal. It further explains how to fill form fields with the retrieved post data and create a fill form method to change the UI state, including adding a cancel button and modifying the edit button.
