JSON.stringify(undefined)
# Barry van Oudtshoorn (13 years ago)
I would assume that this is because the JSON grammar doesn't include "undefined" as an acceptable value -- JSON.stringify({foo:undefined}) returns "{}". Perhaps JSON.stringify(undefined) should, however, return "" -- in my view, this would make more sense.

Calling JSON.stringify(undefined) is essentially the same as calling JSON.stringify()
null is a better representation of a 'empty' value.
