Hi Omer,

This question can be quite daunting at first but do not let it get you down. To pass this you need to use some concatenation with variables and a string in between. You can achieve this with the below code:

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

The # is a string that sits in between the two variables and the variables have been changed to uppercase by the .toUpperCase() method. You concatenate using the +.

Hope this helps! Happy Coding!!!

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

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

We take the id var and use the .toUpperCase() string method to assign it in upper case letters, then we use in the addition operator (+) in order to add another string, '#', then we add the lastName var in upper case letters, too.
