Callback and error handeling examples

Callback and error handeling examples. I guess the question is: which is a better way to write callbacks? Just by seeing what I've wrote now, I can see that one is much smaller, so in terms of code golf option2.js is the better bet, but as far as which is cleaner, I prefer option1.js.

option1.js

something_async({
  success:function(data){
    console.log(data);
  },
  error:function(error){
    console.log(error);
  }
});

option2.js

something_async(function(error,data){
  if(error) console.log(error);
  console.log(data);
});
