Deleting board data with findIndex() and splice()
This will be the last video showing work on the Kanban Task Tracker
In this session, we:
create a component to render a button, and onClick, a pop-up to edit/delete an item
use array methods .findIndex() and .splice() to help us locate and then delete the specified Kanban Task Board from the boards array in our data
troubleshoot some display issues, most notably with z-index and how the z-index of parent components impact their children
