JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Using String Methods

Am I supposed to write the concactenation in id.toUpperCase()? Or somewhere else?

I don't understand how I am supposed to add the id (converted to all caps) + # + lastName together.

id + '#' + lastName made sense to me as the concactenation but aside from that I don't know where to put it or what to put in front of it.

var id = "23188xtr";
var lastName = "Smith";
var userName = id.toUpperCase();
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

You want to add the toUpperCase() method on both id and lastName var. Keep the # in the middle with quotation around it. Something like this bro

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

OK that makes sense, thank you. I guess I was overthinking things.
