---------------------------------------
I did some experiments last night on this. Yes, that is true the JSON spec does
not support these values, and recommend that when stringifying these values, to
convert them to null. What does Windows do in this case, what do they convert
to?
Three approaches:
1. Have a try catch, and reject the serialization attempt, report the error.
Let plugin developers develop their own way to serialize this case -- not sure
this is feasible. At least the app won't crash, but then the app will be in an
indeterminate state.
2. Serialize Infinity and NaN to the string values "Infinity" and "NaN". These
in JavaScript can be coerced into the right values of Infinity and NaN.
However, deserialization is a problem.
3. Serialize Infinity and NaN to null. Again, deserialization is a problem.
For 2 and 3, deserialization may be only a problem for the unit tests with
mixed data to test whether the serialization worked.
Also, for these two cases, we would have to iterate through everything in the
object to serialize to determine if it is a NSNumber (INFINITY or NAN) and
explicitly convert it to the desired value. This may or may not have a
performance impact, depending on how deep objects are nested (for NSDictionarys
for example) - in UIWebView this process is synchronous (and needs to be on the
main thread).
