How to remove inner child object by specific Id?

Below is my json structure:

$scope.dataList = [{
   CompanyName: null,
   Location: null,
   Client: [{
      ClientId: 0,
      ClientName: null,
      Projects:{
         Id: 0,
         Name: null,
      }
   }]
}];

I am trying to remove client data by specific clientid from list of clients but client data is not getting removed and i am not getting any kind of error.

Code:

for (var i = 0; i < $scope.dataList.length; i++)
            {
                for (var j = 0; j < $scope.dataList[i].Client.length; j++)
                {
                    if ($scope.dataList[i].Client[j].ClientId == 101)
                    {
                       $scope.dataList[i].Client.splice(j, 1);
                    }     
                }
            }

Can anybody tell me what is the problem with my code??

This works:

for (var i = 0; i < $scope.dataList.length; i++) {
  for (var j = 0; j < $scope.dataList[i].Client.length; j++) {
    var foundIndex;
    if ($scope.dataList[i].Client[j].ClientId == 101){
      foundIndex = j;
    }
    $scope.dataList[i].Client.splice(j, 1);
  }
}

You can use delete statement for this.

for (var i = 0; i < $scope.dataList.length; i++)
            {
                for (var j = 0; j < $scope.dataList[i].Client.length; j++)
                {
                    if ($scope.dataList[i].Client[j].ClientId == 101)
                    {
                       delete $scope.dataList[i].Client[j];
                    }     
                }
            }

But this will be create problem when you are delete because in for loop one item delete so item count decrease.

So you have to use other way for this.
