Having trouble with challenge 2 of 2 in Stage 2 section=Storing and Tracking Information with Variables

What's the answer? Challenge Task 2 of 2

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".

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>

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".

  1. When seeing the word "adding," think concatenation, e.g. var1 + "#" + var2; Concatenation is like building a sandwich, you can add whatever you want to it using the concatenation operator + to make your String sandwich, if you will. E.g. var mySandwich = "ryebread" + "butter" + "lettuce" + "Jarlsberg" + "herring" + "egg";
  2. It also says to make an "uppercase version." We need to use a method to achieve this and luckily this language comes with one built in for the String class, e.g. var1.toUpperCase() + "#" + var2.toUpperCase();

Put all together, your solution would be something like this: 

var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase() + "#" + lastName.toUpperCase(); 
console.log(userName);

You could also wait, and apply the toUpperCase() method when you use the variable userName e.g. 

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