How to copy object and create new object with existing Json object?

Question

I am trying to create new object that will have some default values from scope.

I found there is copy function to create new independent object.

angular.copy(source,destication)

But its not working for me. I get undefined when I console new object.

angular.copy($rootScope.answers,$rootScope.default);
console.log($rootScope.answers);
console.log($rootScope.default);

In app.js in .run method I trying to use copy function. Please let me know if I am missing anything.

Cloning is an option. Below is an example:

var deepClonedCopy = jQuery.extend(true, {}, originalData);
var clonedData;
clonedData= $.map(deepClonedCopy, function(el) { return el });

Additional answer added:

You need to define $rootScope.default={}; before performing copy.

$rootScope.default={};
angular.copy($rootScope.answers,$rootScope.default);
console.log($rootScope.answers);
console.log($rootScope.default);

Alternatively you can do like this too:

$rootScope.default = angular.copy($rootScope.answers);
