The value for shipping is being set to ['1XT567437'] instead of '1XT567437'. To set the value of shipping to its first element, you can add the line shipping = shipping[0];.

The entire code can be simplified as 

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