JavaScript JavaScript and the DOM (Retiring) Responding to User Interaction Adding an Event Listener

In the button click handler apply the background color of "red" to the warning div.

I don't think I understand the question I put the background color in the function or the click event

app.js 
const warning = document.getElementById("warning");
let button=document.getElementById('makeItRed');
button.addEventListener('click'.warning.style.backgroundcolor='red',function(){

                        });
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Adding an Event Listener</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="warning">
            Warning: My background should be red!
        </div>
        <button id="makeItRed">Make It Red!</button>
        <script src="app.js"></script>
    </body>
</html>

It looks like the problem is how you created the event listener. the addEventListener methods takes in two arguments: the event, and a function. The challenge is asking for an empty function as the second argument

button.addEventListener('click', () => {})

Inside of the function, you make the change to the background color

 button.addEventListener('click', () => {
    warning.style.backgroundColor = 'red';
});

That you I actually figured it out I did that initially but got an error but it was because I forgot to capitalize the C in color thank you for the response
