Can someone explain how this question works? Thanks!

Just not sure where to start? Will this all be on one line?

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

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

Here is the question. Complete the assignment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. In other words, using string concatenation so that the final value of userName is "23188XTR#SMITH".

maybe

 var username = id+"#"+lastName.toUpperCase():

you would first add the ID, than concatenate the "#". and than add the last name when it's uppercased.

Hi Scott, to keep the task result from one to another, you need to separate userName in 2 lines.

First, do the uppercase method to get task 1 done. Then, add # and lastName as uppercase to the already capitalized userName

to avoid a complete spoiler, pseudo as:

userName = id as uppercased ;

userName + = hash + lastName as uppercase

hope it helps, good luck!

I got you Scott. Don't worry. I know it's tough at first. We all go through it.

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

The toUpperCase method needs to be called on each of the variables individually so that each piece gets uppercased. No need to pass anything in them, they don't need any arguments to work their magic. To add a # in between them you simply concatenate the hash in the middle with the "#" with + signs on each side so that it attaches to each of the variables.

Hope that helps. Keep up the coding.
