Given the following 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>
Using console, I'm able to select Wade Christensen with:
$('li').eq(-2);
Why is this throwing an error in the Teamtreehouse editor, but not on localhost?

$('li').eq(2);
About second task. Again I recommend you read documentation about this methods at: https://www.w3schools.com/jquery/jquery_ref_traversing.asp
$('li').eq(2).prev().prev();
