stringify-ordering?

[jessekrubin]

Is the ordering of the string-ify functions inherited from the type definition? How is the ordering determined?

In the object, regular properties (static key named properties) take precedence over dynamic properties.

In the regular properties, optional properties comes earlier than required properties.

Thanks! Just to be clear, optional properties come first? Just curious why that is?

It would be kinda cool if using the stringify function you could create a "canonical" format/ordering/sorting

Closing as answered by the maintainer.

stringify joins regular static-key properties before dynamic properties. Among regular properties, optional properties are emitted before required properties. The implementation references are:

• https://github.com/samchon/typia/blob/master/src/programmers/helpers/StringifyJoinder.ts#L12-L59
• https://github.com/samchon/typia/blob/master/src/programmers/internal/stringify_regular_properties.ts#L77-L81

Do not treat JSON object member order as an interoperability contract outside typia's generated output; if a downstream protocol requires canonical ordering, build that canonical object/string explicitly.
