I don't know what to do?

Finally, add a # symbol and lastName in uppercase to the end of the userName string. the final value of userName is "23188XTR#SMITH".

This is the question that it asked me and i don't know what to do so some help would be great thank you!

app.js
var id = "23188xtr";
var lastName = "Smith";

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

The statement is asking you to convert the id and lastName to uppercase and add # to it. This is known as concatenation. The error with your code is,

  1. You have not converted the lastName to uppercase.
  2. You are adding "#" and uppercase as arguments toUpperCase() and this is wrong.

To get the desired answer which is "23188XTR#SMITH", your code will have to look like something like this.

var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase() + "#" + lastName.toUpperCase();

You have the concatenation of # and lastName as input to your toUpperCase method, which isn't going to work. It should look like this:

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