Using the on() method, attach an event handler to handle click events on the ul element with the class of .student-list.

$('.student-list').on('click', (e)=>{}); what is missing from my answer, it is working fine in my local project.

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
$('.student-list').on('click', (e)=>{
});

Can you explain why the " (e)=> " was used and not: " function (e){});"

Nothing wrong with your code, however the challenge is expecting event to be passed and not e.

$('.student-list').on('click', event => {});

Treehouse can be picky sometimes to ensure people are getting the correct answers.
