angular update $scope variable inside loop

Question

I am trying to update a $scope variable:

ex:

$scope.variable_1
$scope.variable_2
...

I would like to update it this way:

for (i=0; i<2; i++) {    
  $scope.variable_$i = 1;
}

What I need is to get access to the "$scope.variable_1" using the index "i" in each iteration.

any suggestion? Thanks in advance.

In javascript you can access variables by their name :

for (i=0; i<2; i++) {    
  $scope['variable_'+i] = 1;
}

Also, accessing properties this way should be avoided if you can use an array instead.

Correct answer but I don't think one should use variables in such cases! May be Array is the way to go..

Totally agree, added note about this
