Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName v

I am having a hard time to run this code.
var id = "23188xtr"; var lastName = "Smith";

var userName = id.toUpperCase(id);

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

var userName = id.toUpperCase();

You're suppose to use the touppercase on the lastName to turn that into full uppercase!

var lastName = "Smith".toUpperCase();

So the end code looks like:

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

var userName = id.toUpperCase();
