Manage my array values

I have this array $scope.taxarr and I am facing some value which is mention below.

$scope.taxarr = [];
for (var co = 0; co < count_item; co++) {

  $scope.qty_amt = parseInt($scope.newData1[co].quantity) * parseInt($scope.newData1[co].rate);

  $scope.tax_val1 = (parseInt($scope.qty_amt) * parseInt($scope.newData1[co].tax_value)) / 100;


  $scope.taxvalue = parseInt($scope.newData1[co].tax_value);
  $scope.taxid = parseInt($scope.newData1[co].tax_name);
  $scope.loop = $scope.taxarr.length;
  if ($scope.loop === 0) {
    $scope.taxarr.push({
      tax_id: $scope.taxid,
      tax_name: $scope.taxvalue,
      tax_amount: $scope.tax_val1
    });
  } else {
    for (var i = 0; i < $scope.loop; i++) {

      if ($scope.taxid === $scope.taxarr[i].tax_id) {
        $scope.taxarr[i].tax_amount = parseInt($scope.taxarr[i].tax_amount) + parseInt($scope.tax_val1);
        break;
      } else {

        $scope.taxarr.push({
          tax_id: $scope.taxid,
          tax_name: $scope.taxvalue,
          tax_amount: $scope.tax_val1
        });
      }
    }
  }
  console.log($scope.taxarr);
}

I have one array which allows me to check particular id in array object and I face some problem with my inner if ... else part where I check my id if there match value it is update amount else push object as new record

I am working with loop and every time loop provide different array value and compare in if condition.

I need some method that help me find value directly in array object and return in True/False where can i perform my action

why reinvent the wheel?

$scope.$watch(function(){
    return $scope.taxarr;
}, function taxarr_change(newValue, oldValue){
    //do your thing!

}, true)//true is not a must, read in docs
