Finally, remove <li> Element stores in firstListItem

Hello, I am at a lost as to why this isn’t working. Could someone help me out?

let myList = document.querySelector('ul');
let firstListItem = document.getElementById('#first');
<!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>

When using getElementById() or getElementsByClassName you do not need the # or '.' prefix as we already know it is an Id or a class that we want to get, so we just need the text after the prefix.

So in your code example, if you update it as below:

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

you should now be OK, hope this helps :)
