Remove the quotes where you are appending $newStudent.

As Adam mentioned, you're passing in a string to the append method. jQuery will see that as the literal string of "$newStudent" instead of as a variable.

Just remove the quotes:

const $newStudent = $('<li>Sam Smith</li>')
$('.student-list').append($newStudent);

and you're good.
