var id = "23188xtr"; var lastName = "Smith";

var userName = userName + id; userName.toUpperCase();

I tried this. It must be wayyy out of order.

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

var userName = userName + id;
userName.toUpperCase();

So, in your code below, what you are accomplishing is to add (or concatenate) the contents of the userName and id variables and then set that value to be the value of user name. then, you are upper uppercasing this concatenated value.

var id = "23188xtr";
var lastName = "Smith";
var userName = userName + id; //<-- here is where you are concatenating, or added the two variable contents together, under one name, in this case, userName
userName.toUpperCase();

You are doing more than is needed. Lets just set the variable username to have the contents of the id variable, and set the id variable contents to upper case.

var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase(); //here we assign the userName variable to be the upper case contents of the id variable
