The first task is ok in the first check but at the end, it isn't valid. What can i do?

Is it a bug in the app?

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>
app.js 
let myList;
let firstListItem;
myList = document.querySelector('ul');
firstListItem = myList.querySelector('li:first-child');
myList.removeChild('li:last-child');

The challenge is to remove the item you selected from the DOM. Just put firstListItem into the removeChild method and it works fine. Good luck.

let myList; let firstListItem;

myList = document.querySelector('ul'); firstListItem = myList.querySelector('li:first-child'); myList.removeChild(firstListItem);
