Tealium Solutions, I looked over the challenge.

The first part reads as follows: 

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.

So, let's create this shipping variable:

var shipping;

Okay, now that we have created a shipping variable, let's remove the first item from the array. Now, before we remove the first item, let's think, "Is there an available method that can remove the first item?"

Yes. shift()

So, let's add that.

var shipping = orderQueue.shift();

Sweet. Now we are at task two, which reads as follows: 

Now create a new variable named cancelled. Remove the last item from the orderQueue 
array and store it in the variable cancelled. Use the array method you 
learned in the last video for this challenge.

Okay, we used the shift method to pass the first task. Let's ask ourselves, "If I am able to remove the first item, can I remove the last item?"

Yes, part II. pop()

So, let's add that.

var cancelled = orderQueue.pop();

Boom! You should pass.
