Removing an Element from the DOM task 3/3

I'm causing an error but I don't quite know what it is :/

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 = document.getElementsByTagName('ul')[0];

let firstListItem = document.querySelector('li:first-child');

firstListItem.removeChild(li);

:point_right: The calling format for removeChild is parent.removeChild(child);.

Conveniently, in task 1 you identified the parent element, and in task 2 you identified the child. So in task 3, you just need to construct the call by filling in the other variables in the right places.

Hey, James Matthews — did you accidentally hit the wrong button, or was I the victim of a "drive-by downvoting"?

Hello Steven, I can assure you I did not down-vote, and marked as best answer, so I assume you were indeed a victim! I have given you a +1 though, just to counter it ;)

I wasn't concerned about the point, just wondered if it was an error. But thanks!
