javascript - Why does angular $resource add extra objects ($promise, $resolve...) to my data response? -

i return resource url

    $resource("http://foo.com/bar.json").get().          $promise.then(function(data){ $scope.result = data},                    function(error){ $scope.msg = "error" } ); 

resource returns

["item1"...."item_n",.....,"$promise", "$resolved", "$get", "$save", "$query", "$remove", "$delete"] 

why objects in data set. i'm guessing $promise returns , waits server response. once have server response can server data without promise jargon?

if @ angular source here:

https://github.com/angular/angular.js/blob/master/src/ngresource/resource.js#l505

there tojson method on resource prototype chain accomplish you.

for example:

$resource("http://foo.com/bar.json").get(function(res) {     $scope.result = res.tojson(); });
