Can't figure this out. Can someone help me here? Much appreciated.

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

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

How to complete the assigment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. Using string concatenation so the final value is "23188XTR#SMITH."

You are so close! you declared userName (var userName=) and set it to be the concatenation of the var id and a hash and the var lastName. The next line calls the method toUpperCase on the previous value but doesn't assign it to anything. You can set a variable equal to the result of altering itself, for example var counter = 1; //do stuff; counter = counter + 1;.

Yep, you've pretty much got it.

You just need to have the lastName.toUpperCase() as part of the concatenation. Right now you have two separate variables, and lastName is not uppercased.

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

Remember, the lastName variable is what the challenge asked for in uppercase... not userName.

Keep Coding! :) :dizzy:

Just for clarity, the above answer will give you 23188xtr#SMITH, which I believe is what the challenge asks for.

However, to get the result in quote marks from the question, 23188XTR#SMITH, you would need to call the toUpperCase method on both of your string variables, like this:

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