could not solve this, help me please

Inside the jQuery each() method, use prepend() to add an '<input type="checkbox"/>' to the beginning of each list item. Use the this keyword, so the callback function doesn't need any arguments. $('.favorite-things li').each(function() { // Write code here const input = $(this).attr('<input type="checkbox"/>'); $(this).prepand(input); });

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
  const input = $(this).attr('<input type="checkbox"/>');
  $(this).prepand(input);
});

The instructions say to "use prepend()" but the code here has "prepand" (with an "a") instead.

Also, the HTML code for the input can't be used as an attribute name in the ".attr" method. But you don't need to do anything separately with it anyway. The HTML string can be supplied direclty as the argument to the "prepend" method.
