how to store same data in multiple $scope variables in same controller using angularjs

I have to store same data in two different scope variables. I have saved as per below code.

    app.controller('ClientsCtrl', function ($scope, $http) {

        $scope.model = {};

        $http.get("client/getdata", {})
            .then(function (result) {

                //For e.g, I have received result.data.Frequency = 'Weekly'

                $scope.model = {
                    edit: result.data,
                    show: result.data
                };

            },
            function (error) {
            });

    });

Used these scope variables to show and edit like

<div>        
    <div>
       Show Model Frequency: {{model.show.Frequency}}<br /><br />
       Edit Model Frequency: {{model.edit.Frequency}}
    </div>

    <div>
        <md-select ng-model="model.edit.Frequency" aria-label="Frequency">
            <md-option value="Daily"> Daily</md-option>
            <md-option value="Weekly"> Weekly</md-option>
        </md-select>
    </div>
</div>

If once I changed the value in edit model, its also auto change in show model even I stored in different variables.

I want to change the data only after save the data and don't want to display the changing frequency before save.

Because of they have same reference. So you need to create a new reference before the object assignation.

So use angular.copy

$scope.model = {edit:angular.copy(result.data),show:angular.copy(result.data)};

or try this 

$scope.model = {
                edit:JSON.parse(JSON.stringify(result.data)),
                show:JSON.parse(JSON.stringify(result.data))
                };
