Is there anyway to create Javascript object with "default function"? AngularJS

Question

As you may know, AngularJS $http service is allowing to call it with/out specific function, for ex:

1. $http(req).then(function(){...}, function(){...});

2. $http.get('/someUrl', config).then(successCallback, errorCallback);

I would like to get some more information about the way I can implement it on my factory and generally in JS.

Functions are Objects in JavaScript. This means that you can assign other properties and functions on a function.

function foo(){
   //do something
}

foo.bar = function(){
   //do something else
}
