{ Created it because I found that defining the columns at design time isn't much productive.
  Usage:
  Consider CustomersBindingScope is a TBindScope and CustomersGrid is a TStringGrid, and
  CustomerBindingScope.DataObject points to a TList<TCustomer> and TCustomer is declared as
  follow:
  type
    TCustomer = class
    public
      property Name: String read FName write FName;
      property Age: Integer read FAge write FAge;

// # Making our JS code more clear

// ## 1. Initial code. Bad practice.
//
// * Mixed IO and data processing all in one place.  
// * It is not self-documenting, as it is not clear at-a-glance what is happening inside it. 
// * It can not be easily unit tested as it has side-effects (e.g. API calls) mixed in with its output logic.
