What's wrong with my code

What's wrong with my code

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".

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

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

Hi Stian,

Your code does produce the correct result, but I think the challenge wanted you to arrive at the answer in a specific way which Erik has in his answer.

This challenge is worded in a fairly confusing manner, but we can see the end result that they're looking for in the sample string '23188XTR#SMITH'.

In the first task of the challenge, we applied .toUpperCase() to our ID. Now, we need to append a pound sign ('#'), then append to that the all-uppercase version of the value stored in our lastName variable.

You are close, but you have a few issues with your code.

You have:

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

You need:

var userName = id.toUpperCase() + "#" + lastName.toUpperCase(); // retain the id.toUpperCase() call, then simply append the next two things that you need in your string

Happy coding!
