Why JSCore config JSPropertyDescriptorEnumerableKey property 'NO' ?

@phoboslab Thanks for answering!!

And how can I enumerate a JSExport object?

See putNonEnumerable

JavaScriptCore-iOS/JavaScriptCore/API/JSWrapperMap.mm

Line 465 in 544b3a2

putNonEnumerable(prototype, @"constructor", constructor);

JavaScriptCore-iOS/JavaScriptCore/API/JSWrapperMap.mm

Line 150 in 544b3a2

inline void putNonEnumerable(JSValue *base, NSString *propertyName, JSValue *value)
