What am I missing? I am sure it is something simple that I should be able to easily remember...

I don't know why this is failing. Can you just point out what I am getting wrong here? I'll remember the correct answer and not ask about this again, promise.

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

<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>

</html>
app.js 
$('.favorite-things li').each(function() {
  this.prepend('<input type="checkbox">');
});

Within the callback, "this" represent an element, but "prepend" is a jQuery method. So you need to convert "this" into a jQuery object to use "prepend".

Also, the instructions specifically asked you to add "'<input type="checkbox"/>' to the beginning of each list item". Note that it's looking for the XHTML syntax that includes a slash. This wouldn't be necessary in actual practice, so you might want to report it as a bug to the Support folks.

Could you be more specific regarding the, "convert "this" into a jQuery object"?
