Get Array size in Angular-JS

Question

Im trying to get the size of an array but every time the console say me undefined and don't know why.

.success(function (data) {
            console.log('Random-Suffix:' + suffix);
            $scope.builds = new X2JS().xml_str2json(data);

            var size  = $scope.builds.length;
            console.log('Size: ' + size);



            $timeout(function () {
                $scope.exampleLiveDataChange();
            }, 3000);
        })

Try console.log(typeof($scope.builds)) you will most probably see that $scope.builds is not an array ! You may then need to output it and look for your array inside it; — Fourat

From what I read in the X2JS documentation:

<instance>.xml_str2json - Convert XML specified as string to JSON

Maybe builds is not an array, but an object. If the object contains an array like this one:

var test = {one : 'one' , two : [1,2,3]};

If you do:

test.length;

You get:

undefined

If you do:

test.two.length;

Then you get:

Yeah, you are right, thanks. Do you know if is there a way to get the size of an array inside the object?

Yeah, it's easy. What is the structure of the object?
