I'm stuck on this guys, help. I don't know where to add# symbol and how to combine those?

I tried several times, but i dont know where to add + and how to combine those.

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

var userName = (id.toUpperCase());
var lastName = (id.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>

The second challenge is to update the userName variable so that the "#" and an uppercase version of the last name are appended to the value in the first task (which you have already in your answer above). The sample final output is also provided.

Anytime you'd like to add to or combine a variable with a new expression, such as (1 + 'fox') you would use an assignment operator like: userName += 1 + 'fox'; . Hope this helps point you in the right direction. Check out this article for further information: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Assignment_Operators

To concatenate strings, you just add a plus in between the variables. I don't know what your goal is with this but I will give you an example

let firstName = 'Sam';
let lastName = 'Davis';

let fullName = firstName + ' ' + lastName;

the quotes in between firstName and lastName add the space between the names.
