I 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?
1) For adding an item
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
last-child in your remove button event listener
Solution: Remove the space
let li = document.querySelector('li:last-child');
