when on to goolgle to see if there was any help, just libs fighting. I still dont know what I am doing wrong

copied from task 3 of 3

contentDiv.appendChild(newParagraph);

as I see it, it should work!!!

app.js 
const contentDiv = document.getElementById("content");
let newParagraph = document.createElement('p');
newParagraph.className = "panel";

let div = document.getElementByTagName('div');
contentDiv.appendChild(newParagraph);
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>

I don't know what "libs fighting" might be, but it sounds interesting!

But here are some issues I noticed with your task 3 code:

  • you wrote "getElementByTagName" (missing an "s") instead of "getElementsByTagName"
  • "getElementsByTagName" returns a collection and would need to be indexed
  • you might want to use "getElementById" instead
  • "contentDiv" is undefined (did you mean to use your variable named "div"?)
