Why doesn't my code accept?

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

Try putting the input tag string as a parameter of prepend, instead of using a selector on it while assigning it to a const. Im sure someone else can explain why but using a selector on a whole html elements just seems syntactically incorrect.

$(this).prepend('<input type="checkbox"/>');

This would fix it though
