Courses Plus Student 5,631 Pointscannot access 'listDiv' before initialization? Means you need to declare and assigned the variable before you will be able to use it.
and this is the correct way:
// you need to assigned (listDiv) first, then ues it.
const listDiv = document.querySelector('.list');
const listUl = listDiv.querySelector('ul');
// Using parentNode to Traverse Up the DOM
listUl.addEventListener('click', (event) => {
if(event.target.tagName == 'BUTTON'){
// let button = event.target
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
});
