What am I missing here?

From what I remember .shift is remove and .push is add, correct? Can't figure this out

script.js 
var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = [];

orderQueue.shift('1XT567437');
shipping.push('1XT567437');
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

</head>
<body>
<script src="script.js"></script>

</html>

I think they are looking for a simpler solution. When you initialize the "shipping" var, shift the orderQueue item right into it.

var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = orderQueue.shift('1XT567437');

By the way, you would be better off if you shifted by the index number itself... a slightly cleaner solution:

var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = orderQueue.shift(1);
