function UserController($scope, User, Group){

    $scope.users = User.query();

    $scope.isNewUser = function(){

            var len = $scope.users.lenght;
            console.log(len); //undefined

            for(var i = 0; i < len; i++){
                if($scope.users[i].created_at == null){
                    return false;

            return true;

In frontend I have a list of users that are rendered well. However when I retrieve the length I get undefined. Why? I need the length of users to loop through the array of objects.
