On my last nerve trying to get '#' between id and lastName. I've tried everything.

Question

This seems so basic but I've tried every possible way to put '#' between id and lastName.

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

This seems like it would work but I still get the Bummer message. I've tried every different way and nothing works. I've even tried putting '#' into it's own variable and it doesn't work.

app.js

var id = "23188xtr";
id.toUpperCase();
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>

Hi James,

While I haven't completed the current challenge you are working on, I suspect it may be because the id.toUpperCase(); isn't 'saving'. This is because when you call .toUpperCase(); it will return a new string but you are not saving the returned value to a variable.

On the other hand, the output of lastName.toUpperCase(); is being saved as part of the concatenated string to the variable named userName.

I'm assuming that the expected output is "23188XTR#SMITH".

I'll add some comments and tweak the code you provided, to illustrate this:

var id = "23188xtr";

id.toUpperCase(); //=> Returns "23188XTR"
console.log(id); //=> prints "23188xtr"

var lastName = "Smith";

var userName = id + '#' + lastName.toUpperCase();
console.log(userName); //=> prints "23188xtr#SMITH" rather than "23188XTR#SMITH"

Cheers,

Jacob
