I’ve been doing a fair amount of javascript programming lately, and I found myself needing to remove a nested object from an object.  Doing this is easy enough with the “delete” command, but it leaves you with annoying “undefined”s all over.  To get around that, I scoured the internet for a way to remove them easily.  Turns out that if efficiency isn’t a problem, it’s easier to drop the right objects into an array and then re-assign it.

var tmpArray = new Array();
for(el in self.orderData.data.items) {
     if(self.orderData.data.items[el]) {
          tmpArray.push(self.orderData.data.items[el]);
     }
}
self.orderData.data.items = tmpArray;

Easy and pie.
