declaring a promise in angularJS with named success/error callbacks

Question

I am trying to do something very similar to the $http service. From my understanding $http return a promise object.

When using it the syntax is :

$http(.

The nice thing with open-source is that you can read the source. Here's how the $http service does it:

  promise.success = function(fn) {
    promise.then(function(response) {
      fn(response.data, response.status, response.headers, config);
    });
    return promise;
  };

  promise.error = function(fn) {
    promise.then(null, function(response) {
      fn(response.data, response.status, response.headers, config);
    });
    return promise;
  };
