Is it valid to define functions in JSON results?

Question

Part of a website\'s JSON response had this (... added for context):

{..., now:function(){return(new Date).getTime()}, ...}

Is adding anony

Answer 1

Nope, definitely not.

If you use a decent JSON serializer, it won't let you serialize a function like that. It's a valid OBJECT, but not valid JSON. Whatever that website's intent, it's not sending valid JSON.
