The callback invoked when an object is finalized (prepared for garbage collection). An object may be finalized on any thread.
- iOS 7.0+

- tvOS 9.0+
The JSObject being finalized.
If you named your function Finalize, you would declare it like this:
void Finalize(JSObjectRef object);
The finalize callback is called on the most derived class first, and the least derived class (the parent class) last.
You must not call any function that may cause a garbage collection or an allocation of a garbage collected object from within a JSObjectFinalizeCallback. This includes all functions that have a JSContextRef parameter.
