json: HCkJsonObject;

begin
json := CkJsonObject_Create();

// If a number is too large for a 32-bit signed integer, then call UpdateNumber instead of UpdateInt.
// The large integer is passed to UpdateNumber as a string, but in the JSON it will be an integer.

// For example:
CkJsonObject_UpdateNumber(json,'largeNumber','6884556842');

// If the integer is small enough for a 32-bit signed integer, then use UpdateInt:
CkJsonObject_UpdateInt(json,'reasonableInt',123456);

CkJsonObject_putEmitCompact(json,False);
Memo1.Lines.Add(CkJsonObject__emit(json));

// The output:
// Notice the large number passed as a string does not have quotes in the JSON

// {
//   "largeNumber": 6884556842,
//   "reasonableInt": 123456
// }

CkJsonObject_Dispose(json);
