JavaScript Callback Functions in JavaScript Callbacks with Timers Triggering an Animation

I used an anonymous function and an arrow function but neither worked

Hey.

See my code for this challenge. It asked me to apply a timer to this function. I.e. turn the function into a callback.

I don't know why it says: "The callback is not the startAnimation function"

app.js 
const section = document.getElementById("animateMe");

setTimeout(function() {
  //Applies spinning animation to section element
  section.className = "spin";
}, 2000);
index.html 
<!DOCTYPE html>
<html lang="en">
    <head>
        <title></title>
        <link rel='stylesheet' href='styles.css'>
    </head>
    <body>
        <section id="animateMe">
            <p>Animate Me in 2 Seconds!</p>
        </section>
        <script src='app.js'></script>
    </body>
</html>

Hey Samuel Kleos ! You'll just need to call setTimeout() at the end of the file

const section = document.getElementById("animateMe");

function startAnimation() {
  //Applies spinning animation to section element
  section.className = "spin";
}

setTimeout(startAnimation, 2000)
