I cant function 3 to remove the item to work

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

index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <ul>
            <li id="first">First Item</li>
            <li id="second">Second Item</li>
            <li id="third">Third Item</li>
        </ul>
        <script src="app.js"></script>
    </body>
</html>

Check your arguments.

The removeChild method should be used on the parent element, and given the child element (not it's ID) as the passed parameter.

And you've already created variables for both.
