12. Return ? SerializeJSONProperty(the empty String, wrapper).
|
|
|

SerializeJSONProperty ( key, holder )
|

[...]
|
|
2. If Type(value) is Object, then

|
a. Let toJSON be ? Get(value, "toJSON").

i. Set value to ? Call(toJSON, value, « key »).

10. If Type(value) is Object and IsCallable(value) is false, then
|
|
a. Let isArray be ? IsArray(value).

|
b. If isArray is true, return ? SerializeJSONArray(value).
