Finally, append the newParagraph element to contentDiv.

Iv tried various way, Suggestions are Welcome.

app.js 
var contentDiv = document.getElementById('content');
var newParagraph = document.createElement("p");
newParagraph.className = "panel";
contentDiv.appendchild(newParagraph);
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>

In testing your code I received a different error:

Bummer: There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'contentDiv.appendchild(newParagraph)')

This is because the C in appendChild should be uppercase.

Good catch. I missed that.

The third line, where you attempt to add a class to the new Element, is incorrect.

To attach a CSS class to an element via code we use the classList property which has a method called, add().

It should look like:

newParagaph.classList.add('panel');
