/**
 Compares two items (values or references) for nested equivalency, meaning that
 at root and at each key or index they are equivalent as follows:

 - If a value type, values are either hard equal (===) or are both NaN
     (different than JS where NaN !== NaN)
 - If functions, they are the same function instance or have the same value
     when converted to string via `toString()`
 - If Date objects, both have the same getTime() or are both NaN (invalid)
 - If arrays, both are same length, and all contained values areEquivalent
