Go by Value in JSON in precise?

Question

Hi,

 

I have watched an interesting conduct in JSON,

 

Give me a chance to endeavor to depict situation, we have one rakish degree variable say

 

$scope.regValue = 0;

 

This is instated in the controller and utilized under ngModel in HTML layout to find an adjustment in esteem.

 

Presently Let's allocate this to JSON protest key,

 

var jsonObj = { 'key1': $scope.regValue };

 

What I have watched is, presently

 

jsonObj['key1']

 

the esteem will be 0, which is Correct.

 

Yet, when ngModel changes the estimation of $scope.regValue, It isn't reflected in JSON key esteem, which implies

 

jsonObj['key1']

 

is as yet equivalent to 0.

 

While $scope.regValue has effectively changed.

 

Is this conduct expected, Or Pass by reference can't pass its own reference to another variable?

 

Thanks and Regards,
