I am so lost on this entire lesson...

See my attached code...

app.js 
var body = document.body;
var newParagraph = document.createElement("p");
var pleaseEnableParagraph = document.querySelector("#please_enable");

//Remove "Please Enable JavaScript" paragraph

  body.removeChild("#please_enable");


//Append new paragaph to document
index.html 
<!DOCTYPE html>
<html>
  <body>
    <p id="please_enable">Please Enable JavaScript</p>

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

In your code you have: body.removeChild("#please_enable");

instead of passing in "#please_enable" you should use the var that was set up to get this from the DOM.

var pleaseEnableParagraph = document.querySelector("#please_enable");

so it would look like this : body.removeChild(pleaseEnableParagraph);

using the ID selector will not work with the removeChild() method.

I had no clue what to do after watching the video (and other video's in this course or the javascript fundamental courses). But with common sense, and looking stuff up in MDN I still managed to get this far.

The Javascrift basics course is much better to follow. So it would be great if this course Interactive web pages with javascript would be reviewed and altered to make it more comprehensive.

(ps perhaps when I do the course a second time, after I finish the javascript basics, everything falls in place)
