i have been doing a lot of the videos per day and have forgotten how to put document.write into the html body.

the question asks me to use the document.write function to print the player variable onto the page and i have forgotten how to do that.

app.js 
var player = 'Jasmine'
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="app.js"></script>
</body>
</html>

Hello Troy Document.write() is JavaScript that must be written in the app.js file

If it was to be written in the index.html file it would need to be contained with in a script tag which is not recommended.

JavaScript is written in a .js file to avoid cluttering html and JavaScript together among many other reasons.

Any function call is just the name of the function followed by parentheses. Any argument(s) passed to the function go between the parentheses:

title = "<h1>This is a title</h1>";
document.write(title);

The body is the document object. So .write is a method on the document object. When you call document.write(); it’s 100% going to print out to the body because the body is part of the document object.

Just put in document.write(player); in the app.js file and you will see from that point it will click.
