Hi,

the string that the challenge asks for is "23188XTR#SMITH". This string is composed of 3 parts:

1) the content of id in all uppercase letters

2) the # and

3) lastName in all uppercase letters

If you combine all three parts by string concatenation, you obtain the string that is asked for. Defining the variable userName as id.toUpperCase() is part of task 1 of the challenge. That's why we first define it like that, then add the rest of what is asked for to userName in a different step, so that userName finally stores "23188XTR#SMITH".

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

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

Thank you for answering this question. I was going to ask the same question too.
