Sample JSON

{
  "name":"Onur YILDIZ", 
  "vip":true,
  "telephones":["000000000","111111111111"],
  "age":24,
  "size":1.72,
  "adresses":[
    {
      "adress":"blabla",
      "city":"Antalya",
      "pc":7160
    },
    {
      "adress":"blabla",
      "city":"Adana",
      "pc":1170
    }
  ]
}

Delphi Code

var
  X:ISuperObject;
begin
  X :=TSuperObject.Create('{}');

  X.B['vip']:=true;
  with X.A['telephones']do

   Add('000000000');
   Add('111111111111');
  end;
  X.I['age']:=24;
  X.F['size']:=1.72;
  with X.A['adresses'].O[0]{AutoCreate}do
  begin
    S['adress']:='blabla';

    I['pc']:=7160;
  end;
  // or

Super Expression

const
  JSON ='{ "o": { '+
         '    "1234567890": {'+
         '    "last use date": "2010-10-17T01:23:20",'+
         '    "create date": "2010-10-17T01:23:20",'+
         '    "name": "iPhone 8s"'+
         '        }'+
         '  },'+
         '  "Index": 0, '+
         '  "Data": {"Index2": 1}, '+
         '  "a": [{'+
         '    "last use date": "2010-10-17T01:23:20",'+
         '    "create date": "2010-11-17T01:23:20",'+
         '    "name": "iPhone 8s",'+
         '    "arr": [1,2,3] '+
         '  }, '+
         '  {'+
         '    message: "hello"'+
         '  }]'+
         '}';

var
  X:ISuperObject;
  NewJSon:ISuperObject;
  NewArray:ISuperArray;
begin
  X := SO(JSON);
  ShowMessage( X['o."1234567890"."last use date"'].AsString);
  ShowMessage( X['a[Index]."create date"'].AsString);
  ShowMessage( X['a[Data.Index2].message'].AsString);
  X['a[0].arr'].AsArray.Add('test1');
  // -----
  NewJSON:= X['{a: a[Index], b: a[Data.Index2].message, c: o."1234567890".name, d: 4, e: a[0].arr[2], f: " :) "}'].AsObject;
  NewArray:= X['[a[Index], a[Data.Index2].message, Data.Index2, Index, 1, "1", "test"]'].AsArray;
end;

Variant

var 
  X:ISuperObject;
begin 
  X :=TSuperObject.Create;
  X.V['A']:=1;
  X.V['B']:='2';
  X.V['C']:=1.3;
  X.V['D']:=False;
  X.V['E']:=Null;
  Memo1.Lines.Add(X.AsJSON);
end;

Output

{"A":1,"B":"2","C":1.3,"D":false,"E":null}

         Obj.Next;
      end;
      Memo1.Lines.Add('------');
    end;
end;

OR (Enumerator)

var
  X:ISuperObject;
  AMember,
  OMember:IMember;
begin
  X :=TSuperObject.Create(JSN);

  forAMemberin X.A['adresses']do
  begin
      forOMemberinAMember.AsObjectdo
          Memo1.Lines.Add(OMember.Name+' = '+OMember.ToString);

      Memo1.Lines.Add('------');
  end;

Output

adress = blabla
city =Antalya
pc =7160
------
adress = blabla
city =Adana
pc =1170
