Halp Plz

No idea how to do something this simple...tried every combination I could think of...forgive my stupidity please (and give a working example plz)

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

//Remove "Please Enable JavaScript" paragraph

removeChild.(pleaseEnableParagraph);

//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>

You're just missing one thing; the parent from which you are removing the child! So when you use .removeChild(); you must identify the parent. Have a look at this:

body.removeChild(pleaseEnableParagraph);

You can't just call removeChild() without specifying a parent. Since the please_enable element is a child of body and you already have a variable for that, you can call this and it should work:

body.removeChild(pleaseEnableParagraph);
