229,201 PointsLooking at this line:
let listItems = document.getElementsByTagName("ul")[0];
This won't select a collection because the index ([0]
) will limit the result to just the first element.
Also, the selector is targeting the unordered list itself (ul
) and not the list items within it (li
).
