Javascript Concatenation Question

Cheri,

You have a couple of minor syntax errors here that are easy to make, and unfortunately more difficult to spot! Let's take a look:

You have two issues that I see:

var id = "23188xtr";
var lastName = "Smith";
var userName // issue #1
userName = id.toUpperCase();
userName += '#' + 'lastName.toUpperCase(); // issue #2

Issue #1: Firstly, in this case, it is not necessary to declare your userName variable and set your variable on separate lines; you can easily do this all on one line right out of the gate: var userName = id.toUpperCase();. It isn't technically WRONG to first declare and then separately set your variable, but if you are going to do that, you'll want to make sure you close every statement with a semi-colon. In this case, your variable declaration (i.e. var userName) is missing a closing semi-colon.

You have:

// notice there is no semi-colon after 'userName'
var userName

You want:

// notice there is now a semi-colon after 'userName'
var userName;

Issue #2: You have an extra single quote just before "lastName" here. Remove that quote, and this line is good to go.

You have:

// notice the extra single quote (i.e. ' ) just before "lastName"
userName += '#' + 'lastName.toUpperCase();

You want:

// notice the single quote (i.e. ' ) has been removed before "lastName"
userName += '#' + lastName.toUpperCase();

Other than those two small errors, things look good! One of the most troublesome parts of any programming language is making and finding these tiny errors. They will happen all the time, and are among some of the most difficult things to debug, because they're so easy to miss!

Hope this helps!
