As far as I know, `typeof` works on everything, but for Objects will only yield "object". You then should use `instanceof` to determine the type of object, if necessary. Typically, once I know it's an object I just use it, so that people can provide "non-traditional" but otherwise valid implementations. Only exception is if I'm specifically looking for a Date or DOM Node or other built-in type. EDIT: Of course, I forget that arrays also have `typeof` "object"... Again, probably best to just start using length and indexing and hope for the best.
