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).

|
|
2. If Type(val) is Object, then
|
|
a. Let isArray be ? IsArray(val).
|
|
b. If isArray is true, then

c. Else,

7.2.2 IsArray

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.
