How do I add a character such as the # before a word using concatenation? The var smith example would output #smith

Im trying to ad two variables togther but add a # in front of the second.

app.js 
var id = "23188xtr";
var lastName = "Smith";
var userName = (id + '#' + lastName.toUpperCase());
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>

You need to set the ID to upper case too.

The concatenation is correct, but the challenge will fail if ID is not uppercase.

var userName = (id.toUpperCase() + '#' + lastName.toUpperCase());

You can also add toUpperCase() in one shot by grouping with parentheses.

var userName = (id + '#' + lastName).toUpperCase();
