javascript - Duplicating Angular response data so changes to one don't affect the other -


i have angular controller connected node/express server. response data request called in $http.get can set response=$scope.x. x can interacted , changed. set $scope.y = $scope.x, , changes y result in x changing well. however, want clone response have original response data set different variables without them changing each other.

consider response response.name = "joe".

$scope.x = response; $scope.y = response; 

in code or view/model change x.name such:

$scope.x.name = "bob" 

however, $scope.y.name still equal "joe".

i use 2 separate requests retrieve same response, i'd pass response function dynamically change data , make new version of based on for loop. there clean, "angular" this? or simple javascript function?

angular has built in utility angular.copy()

$scope.x = response; $scope.y = angular.copy(response); 

can used clean out unwanted properties angular can create such hashkeys used in ng-repeat tracking

angular.copy() docs
