instead of the shift method can't you use the splice method to remove from one array and put it into a new array?

script.js 
var orderQueue = ['1XT567437','1U7857317','1I9222528'];
var shipping = orderQueue.splice(0);
index.html

hi Yes you can do but this is a specific challenge so you cannot do it here. you have to understand the difference as well between shift and splice methods.

  1. shift method --- The shift() method removes the first element from an array and returns that element. This method changes the length of the array. 2.splice method -- The splice() method changes the contents of an array by removing existing elements and/or adding new elements by providing the index value for example. var myFish = ['angel', 'clown', 'mandarin', 'sturgeon'];

myFish.splice(2, 0, 'drum'); // insert 'drum' at 2-index position // myFish is ["angel", "clown", "drum", "mandarin", "sturgeon"]

myFish.splice(2, 1); // remove 1 item at 2-index position (that is, "drum") // myFish is ["angel", "clown", "mandarin", "sturgeon"]
