Can anyone point out the syntax error in this problem?

Don't know what I'm doing wrong

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h2>My Favorite Things</h2>

    <ul class="favorite-things">
        <li>Kittens</li>
        <li>Rainbows</li>
        <li>Unicorns</li>
        <li>Sprinkles</li>
    </ul>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
$('.favorite-things li').each(function() {
  // Write code here
  this.prepend('<input type="checkbox"/>');
});

The "this" inside an "each" refers to a DOM element. So to be able to call jQuery methods, you need to convert it to a jQuery object ("$(this)").
