Angularjs can't get array length

Question

I am trying to get the array length, when i console log

console.log($scope.community)

I do get a return, but when i try doing the method i found online , like Get the object length in angularjs is undefined

   var array = Object.keys($scope.community);
   var len = array.length;
   console.log(len)

I am returned with 0 and no error

Array call :

    var all = displayAll.callAll()
        .then(function(response) {
           $scope.all = response;
           for (var i=0; i< $scope.all.length; i++) {

                if ($scope.all[i].CATEGORY == 'Community')
                {
                    $scope.community.push($scope.all[i]);

                }

please show the result of your console.log($scope.community) — holydragon, Oct 25 '18 at 03:43
Please show the whole code that includes how you get your data into $scope.community and how you console.log() it. It may be caused by asynchronous request. — holydragon, Oct 25 '18 at 03:50
Hmm yeah, i forgot about that. Think it might be asynchronous as I am fetching a http call from my factory — HangulSR, Oct 25 '18 at 03:51
Now that if you call console.log($scope.community.length) after the for loop, you should get the length. — holydragon, Oct 25 '18 at 03:53
Yeah, got it. Any way to access it outside? I need to pass the length somewhere — HangulSR, Oct 25 '18 at 03:54
You have to access the length after the request is done, so you will have the correct value. — holydragon, Oct 25 '18 at 03:56

var len = $scope.community.length;
console.log(len);

should return the length of the community. Plus this method can also be used in Native JS, even without using AngularJS.
