Should'n't we NOT declare again the exports object in the loose augmentation pattern example code ?

Hi all, If you do so, the awesomeNewModule is simply re-initialized... or am I missing the whole thing ? I've rewritten the example so it would work for me.

var someModule =  {
  baba: 8
}

var someModule = (function(augmentMe) {
  augmentMe.bibi = 4;

  augmentMe.bonjour = function() {
    console.log("bonjour");
  }
  return augmentMe;
}(someModule || {}));

someModule.bonjour();
console.log(someModule.baba, someModule.bibi);

I'm surprised to be the first to ask, so please tell me if got something wrong. Thanks.

I believe you're correct. Reassigning exports to a new object literal seems like it would overwrite any previous properties of that object if it already exists.
