JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Removing Items from an Array

Don't get it. Please help.

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.

This how I solved. var orderQueue = ['1XT567437','1U7857317','1I9222528']; var shipping = ['1XT567437']; orderQueue.shift(0); shipping.push('1XT567437');

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

You could use just splice(index,n) too:

orderQueue.splice(0, 1);

The splice function removes N items from your array, starting from the index.
