Deep equal with sorted keys in an object.

Is there a way to perform a deep equal to check if the keys are in a defined order? example:

let a = {
   a: 1,
   b: {
     a: {
        a: 1,
        b: 1
      }
    }
};

let b = {
  b: {
    a: {
      b: 1
      a: 1,
    }
  },
  a: 1
};

Here a is equal to b as they have the same properties. But since they are not in the given order, i would like for the test to fail.

I think deep.ordered.keys sounds like a fantastic assertion to add!

@ancmikesmullin unfortunately this is no longer true. The ES6 and above specs specify that keys are ordered by creation order.
