Using var userName = userName.toUppercase(); will assign the content of userName to itselft with all uppercase letters.

My original answer was just a way to show you how to use the method. The correct answer to the question is: 

var userName = id.toUpperCase();

Note: there was a typo on the original answer 'case' should be 'Case' in toUpperCase(). Cheers.
