What do you mean by "native JS JSON"?
JSON ("JavaScript Object Notation") is a standardized format for string
representations of objects. "JSON.stringify" creates this string
representation for a given object, "JSON.parse" creates a new object from
this string representation. If you want to transfer a string, and then
create an object from it, then JSON.Parse (which is exposed as
V8::JSON::Parse in the V8 API) is the way to go.
(Depending on your use case, instead of transferring a JSON string, passing
around an ArrayBuffer with externalized data might be a better fit. Then
there would be no conversions to string and back.)
