I am appending the newParagraph to the body. why isn't it working?

Please help.

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

//Remove "Please Enable JavaScript" paragraph

var p = pleaseEnableParagraph.parentNode
p.removeChild(pleaseEnableParagraph);
//Append new paragaph to document
newParagraph.append(body);
index.html 
<!DOCTYPE html>
<html>
  <body>
    <p id="please_enable">Please Enable JavaScript</p>

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

Hi Chris,

You don't need to set up a new variable for the parent as 'body' is already defined. You just need to removeChild from body.

Then you need to append the newPara to the body. Try it this way:

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

//Remove "Please Enable JavaScript" paragraph

body.removeChild(pleaseEnableParagraph);

//Append new paragaph to document

body.appendChild(newParagraph);

For some reason it registered as a comment not an answer...

2 problems that I can see..

1) you don't have anything added to the new paragraph. 2) append is not the correct method. Try appendChild(); Mozzila Documentation

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

//Remove "Please Enable JavaScript" paragraph

var p = pleaseEnableParagraph.parentNode
p.removeChild(pleaseEnableParagraph);
//Add text to the new paragraph
var newContent = document.createTextNode("Your new Paragraph"); 

newParagraph.appendChild(newContent)
//Append new paragaph to document
body.appendChild(newParagraph);
