Removing items from arrays Challenge Task 1

Hi can can any one help am stuck on the first challenge question for this video.

"Challenge Task 1 of 2

The orderQueue array contains a list of customer orders. Create a new variable named shipping -- remove the first item from the array and place it in the shipping variable. "

The error am getting

Bummer! It doesn't look like you stored the first item from the array in the shipping variable.

My Code.

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

Hey Chris,

the 'shift' method removes the first element of the list and returns it.

This is how one does it:

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

Also, square brackets are creating a list literal. So when you write ['1XT567437'], you create a list that contains the String '1XT567437'.
