Remove the list item element stored in firstListItem from the DOM.

Hi everybody,

I have some problemi with this question. I tried in this way but it tells me it's wrong:

'''li.removeChild(firstListItem);'''

Can you help me? Thanks

If this is for the challenge (your post was linked to a video, not a challenge), try:

let myList = document.querySelector("ul");
let firstListItem = myList.querySelector("li");
myList.removeChild(firstListItem);

Demo:

<!DOCTYPE html>
<html>
<body>
<p>An unordered list:</p>
<ul>
  <li id = "remove">Coffee</li>
  <li>Tea</li>
  <li>Milk</li>
</ul>
<script>
var child = document.getElementById("remove");
var parent = child.parentElement;
parent.removeChild(child);
</script>
</body>
</html>

produces:

An unordered list:
Tea
Milk

Finding:removeChild should be okay as long as the elements are populated and have the correct relationship. You might want to look at how you're populating the firstListItem and li variables, or ensure that the html structure reflects how you select these.
