I am confused as to where to apply the .toUpperCase string method to which variable

I am not sure how to apply the .toUpperCase string method to the id variable and the UserName variable.

app.js 
var id = "23188xtr";
var lastName = "Smith";

var userName
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>

lastName.toUpperCase(), Type it in your console and you'll get "SMITH" or set a variable : var myVar = lastName.toUpperCase(); and check by doing console.log(myVar);

The userName variable is undefined so it won't work.

sorry, meant id.toUpperCase(), but it works the same
