This example is about listing all functions and objects in $scope. $scope is also one Javascript object. By listing key value pairs of $scope, we can list down all functions and objects.

Example Code

Here functionArray, varArray arrays are variables and fun1 is function. We have to list them in same types.
$scope.functionArray = [];
$scope.varArray = []; 
$scope.fun1 = function() {  
};

Code to List Down Functions And Variables

Here key represents name of variable or function. We can verify functions with angular.isFunction and objects or variables with angular.isObject 
$scope.listFunAndVar = function() {
    var obj = $scope;
    for (var key in obj) {
        if (obj.hasOwnProperty(key)) {
            if (angular.isFunction(obj[key])) {
                $scope.functionArray.push(key);
            } else if (angular.isObject(obj[key])) {
                $scope.varArray.push(key);
            }
        }
    }

};

Default $scope objects

AngularJS defines some objects to $scope. Those are "this","$$listeners","$$listenerCount","$parent","$$watchers"
