Recently I have seen a code in the production that is

 if (!angular.isUndefined(newVal)) {
   if(!angular.isUndefined(newVal.min)){
     $scope.dataPoints.min = newVal.min;
   }
   if(!angular.isUndefined(newVal.max)){
     $scope.dataPoints.max = newVal.max;
   }
   if(!angular.isUndefined(newVal.yellowRangeMin)){
     $scope.dataPoints.yellowRangeMin = newVal.yellowRangeMin;
   }
   if(!angular.isUndefined(newVal.yellowRangeMax)){
     $scope.dataPoints.yellowRangeMax = newVal.yellowRangeMax;
   }
   if(!angular.isUndefined(newVal.redRangeMin)){
