Hi Chris!

This passes both tasks:

const orderQueue = ['1XT567437','1U7857317','1I9222528'];

const shipping = orderQueue.shift(); // Task 1

const cancelled = orderQueue.pop(); // Task 2

Keep in mind:

1) shift removes an item from the FRONT of the array

2) unshift adds an item to the FRONT of the array

3) push adds an item to the BACK of the array

4) pop removes an item from the BACK of the array

And all four are functions, so you have to call them with ().

Also, after both operations, orderQueue === ['1U7857317']; // The middle value only, because the other values were removed.

(=== is equal to, of course)

I hope that helps.

Stay safe and happy coding!
