How do I set the class of the newParagraph element?

I don't know where to go from here.

app.js 
const contentDiv = document.getElementById("content");
let newParagraph = document.createElement('p');
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">

        </div>
        <script src="app.js"></script>
    </body>
</html>

There's a couple of handy ways.

If you're setting the only class, you can just assign the className property of the newParagraph. Tha'ts probably all you need for this challenge. But if you ever need to add a class without affecting any already present, you can call the classList.add() method and pass the new class as the argument.
