Feature: Add a "reviver" function to jsonify

[reinhard-sanz]

Is your feature request related to a problem?

I admit a very niche usecase, but i still think a potentially useful one.
I've got a Sveltekit app and i am sending db data from the server to the client. Sveltekit is able to to send POJOs to the client, and is even auto parsing Date instances accordingly, so the user does not need to add special handling to stringify and parse said Date.
What it (logically) is not able to handle stuff like RecordId, which can be nicely handled with jsonify though.
The thing if jsonify parses datetimes into strings, reintroducing the need to add some special handling on the client side to parse the datetime strings back into Date instances.

Describe the solution

It would be nice to have some sort of reviver function on jsonify. Similar to the reviver of JSON.parse(). Enabling users to add custom handling to specific fields if needed. This would enable me to easily ignore Date during conversion.

Maybe something like this:

return jsonify(entries, (key, value, resolve) => {
	// If value is instance of Date, do nothimg 
	if (value instanceof Date) {
            return value;
	}

        // on every other case call the default value resolve function
	return resolve(value);
});

Alternative methods

Implementing some custom handling like this:

const test = JSON.parse(JSON.stringify(users), (key, value) => {
	// one needs to know the keys to be able to do this
	if (key === 'datetime_field') {
		return new Date(value);
	}
	return value;
});

This seems very resource intensive and requires prior knowledge of the data structure.
