How do I solve this challenge?

Finally, remove the <li> element stored in firstListItem from the DOM.

Bummer: There was an error with your code: ReferenceError: Can't find variable: ul

var myList=document.querySelector('ul');
var firstListItem=document.getElementById('first');

let li= document.querySelector('li');
<!DOCTYPE html>
        <title>DOM Manipulation</title>
    <link rel="stylesheet" href="style.css" />
            <li id="first">First Item</li>
            <li id="second">Second Item</li>
            <li id="third">Third Item</li>
        <script src="app.js"></script>

First thing I would try is passing in the variable firstListItem as the argumment to rather than document.getElementById('first')

You'll also need to store a ul variable in your code because it's looking for that where you're trying to remove the child node but it's not finding it. Could be solved my replacing that with myList. Try messing around with that and post back if you're still having some trouble. 🙂
