How come this simple jquery function is not working?

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

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h2>Student List</h2>

    <ul class="student-list">
        <li>James McAvoy</li>
        <li>Alena Holligan</li>
        <li>Wade Christensen</li>
        <li>Matt Krzyzynski</li>
    </ul>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
let newStudent = $('.student-list').append('<li>Sam Smith</li>');

It looks like you're on task 2, but the code that should have been there to pass task 1 is missing. Remember the hint given in every challenge: "Important: In each task of this code challenge, the code you write should be added to the code from the previous task."

The code for task 1 would not have had any class reference or an "append" method. But it would also need a different variable name, this code has "newStudent", but the instructions ask for "a variable called $newStudent" (note the dollar sign).

Then, when you do get to task 2, add additional code on a new line that uses the variable created in task 1 to perform the "append".
