5,427 PointsI can't add an item or remove an item after adding an event listener to the parent element...
It was working fine and then I added the Event Listener to the parent element instead of the list items. Now I cant add a new item or remove an item on the page. Can anybody help me figure out what Im missing?

In index.html your Add item button has class="description"
<button class="description">Add item</button>
However in app.js you are trying to select the button with class="addItemButton"
const addItemButton = document.querySelector('button.addItemButton');
This leads to the following error displayed in the console:
Uncaught TypeError: Cannot read property 'addEventListener' of null
Solution: Change the class to "addItemButton"
<button class="addItemButton">Add item</button>
2) For removing an item
If you check the console when clicking the remove button you will see:
'li: last-child' is not a valid selector.
This is due to the space between li: and last-child in your remove button event listener
Solution: Remove the space
let li = document.querySelector('li:last-child');
