You are incomparable!

Thanks Erik! Really interesting and very usefull in my daily work!

Thanks for the video! One thing that comes to mind is that JsonObject doesn't guarantee the order of keys, I believe. So J1.ReadFrom('{"Test":123, "Test2":456}') will not necessarily equal J2.ReadFrom('{"Test2":456,"Test":123}') when you format them, while they are in fact deeply equal key-value pairs. I've not tried the Format comparison (whether the objects were made via ReadFrom, Add or Clone methods) but I think you'd need to loop through J1.Keys + J1.Values (either shallow comparison or deep/recursive comparison) to know if two JsonObjects are equal (where the order of keys doesn't matter).

You're right, good chatch!

The system id trick is a bit dangerous since it is really more reference equality, wheres FORMAT(x) == FORMAT(y) is value equality. It should also be noted that the records x and y might have different system ids in the database, but the record could be the same in-memory. The system id can be altered in-memory (not modified to DB) making them have the same. One could also fetch the same record as x and y, alter some other fields, suddenly FORMAT(x) != FORMAT(y) while x.SystemId == y.SystemId.

Agreed, it's an imperfect solution, if only the platform had a Record.Compare() function :)
