How do I sort an array of objects based on the ordering of another array?

I stepped in this problem and solved it with a simple .sort

Assuming that your list to be sorted is stored in the variable needSort and the list with the order is in the variable order and the both are in the same scope you can run a .sort like this:

needSort.sort(function(a,b){
  return order.indexOf(a.id) - order.indexOf(b.id);
});

It worked for me, hope it helps.
