The code challenge won't accept my empty function as a parameter what the correct way to add an empty function

the second parameter is what is giving me the error

app.js 
const warning = document.getElementById("warning");
let button =  document.querySelector("button");

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

Hi Mickey

Remember if you have no parameters/arguments you express an arrow function with empty brackets

const warning = document.getElementById("warning");
let button = document.getElementById("makeItRed");

button.addEventListener("click", () => {

});
