  7. If IsCallable(reviver) is true, then
     a. Let root be ObjectCreate(%ObjectPrototype%).
     b. Let rootName be the empty String.
     c. Let status be CreateDataProperty(root, rootName, unfiltered).
     d. Assert: status is true.
     e. Return ? InternalizeJSONProperty(root, rootName).

  3. If argument is a Proxy exotic object, then
     a. If the value of the [[ProxyHandler]] internal slot of argument is null,
        throw a TypeError exception.
     b. Let target be the value of the [[ProxyTarget]] internal slot of
        argument.
     c. Return ? IsArray(target).
