JavaScript – The Definitive Guide – Book
The for/in statement loops through the enumerable properties of an object. Not all properties of an object are enumerable, however: properties added to an object by JavaScript code are enumerable, but the predefined properties (such as methods) of built-in objects are not usually enumerable. The propertyIsEnumerable() method provides a way to distinguish between enumerable and nonenumerable properties. Note, however, that the ECMAScript specification states that propertyIsEnumerable() does not examine the prototype chain, which means it works only for local properties of an object and does not provide any way to test the enumerability of inherited properties.
