A book I've read  (by Patrick Carey) says Javascript supports 4 variable
numeric, string, Boolean, and null.
Is a Date object variable considered one of these types? If so, which one?
Or did Carey just leave off another type of variable (Object)?
I searched the FAQ using "data type" as the phrase with no result.

Thanks - Hal
