hey @itavy - yes it is intended (see #77)
This is to do with the JSON spec (try JSON.stringify({foo: undefined})
, and see https://en.wikipedia.org/wiki/JSON#Unsupported_native_data_types)
The undefined
type isn't supported in JSON
We could consider putting undefined
values into a string "undefined", this behaviour could be enabled by a option flag - cc/ @mcollina
