I'm still stuck
whats wrong in my code
var id = "23188xtr"; var lastName = "Smith"; var userName = id.toUpperCase("=+23188xtr");

The toUpperCase() method does not take any parameters.
To build up the final result, you might use concatenation (indicated by a + symbol) between individual strings to "stick them together".
