Use jQuery to append your new element to the unordered list with the class of student-list.

I'm lost on this one, brain fart maybe?

Help is appreciated!

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 
var $newStudent = $('<li>Sam Smith</li>'); 

$ append('.student-list');

//     <ul class="student-list">

You've got the selector, and the "append", but you still need a reference to the element being added, and they all need to be re-arranged a bit. The selector is used to create a jQuery object, then you use the "append" method of the object and pass your new element as the argument:

$('.student-list').append($newStudent);

Great answer. I'm super impressed with your 95,000 points by the way!

That was a tough call,

You both gave great answers but Dale was 2 minutes before you.

I figured it would be "best etiquette" to give "Best Answer" to the first answer that was good.

That's a good practice, but you may have misinterpreted the times.
If you hover your mouse over the "ago" time it will show you the exact time each message was given.

Sorry for the confusion,

I just asked another question that I'm confused on and I'll give you first dibs:

Modify this object so it uses two properties firstName and lastName and remove their variable declarations

Done. I'm a rookie with the question feature on this site, this was my first question, but things are starting to get challenging on the Full Stack JavaScript Track.

Thanks for your answer! I was stuck trying to figure out what I had done wrong and I mistakenly added quotes around $newStudent

Hi Zach,

Use jQuery to select .student-list, then call the append method with $newStudent as a parameter.

$('.student-list').append($newStudent);

Thanks Dale,

I way over thought this and it's been a year since I used jQuery so I moved through this lesson to quickly.
