I'm stuck in here!

How to use string methods?, the video is not that descriptive!

var id = "23188xtr";
var lastName = "Smith";

var userName
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
<script src="app.js"></script>

Simple take the string and paste this directly after it: .toUpperCase()


var myName = "John";

//This will read: John

myName = myName.toUpperCase();
//This will read: JOHN

See, you var 'id' holds a string here, a combination of numbers and letters, so what you need to do to 'capitalise' it, is to run toUpperCase method.
