Defining various scopes in Angular-Rails through user-defined input

Depending on user input, I have a range of 1 to 5 lists with arrays of items in each. The lists are named list1, list2... When I declare $scope using $scope.list = [], it doesn't specify which list it is referring to. While I could statically declare each list since there's a limit of 5, it feels inefficient. Is there a more efficient way to declare each list based on user input?

One way to dynamically add a property to your $scope is by treating it like any other regular javascript object.

For example, both $scope.myList = [] and $scope['myList'] = [] achieve the same result.

By taking input from users, you can easily create these list properties on your scope based on their input.

A simple Psuedo-code implementation could look like this:

$scope.onUserInput = function(){
     // userInput is assumed to be a number
     for (i = 0; i < userInput; i++){
         $scope['list' + (i+1).toString()] = [];
    }    
}
