How do I get the .parentNode method to work so I can get the paragraph removed using the remove child method?

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

//Remove "Please Enable JavaScript" paragraph newParagraph.parentNode; body.parentNode; body.removeChild("p"); ...

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

//Remove "Please Enable JavaScript" paragraph
newParagraph.parentNode;
body.parentNode;
body.removeChild("p");
//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>

Hi Jonas,

Task 1 can be solved with 1 line of code and also parentNode is not needed to solve it although you could use it.

You almost have it with body.removeChild("p"); except that instead of passing in the string "p" you want to pass in the child node that you're trying to remove. This node was saved in a variable named pleaseEnableParagraph
