WriteLine ' Change the value of p1 properties and display the values of p1 and p2. As the output from the example shows, when a Person object is cloned by calling the method, the cloned Person object is an independent copy of the original object, except that they share the same Person. I like your style — low coupling.

For copying property definitions, including their enumerability, into prototypes and should be used instead. Object B, in turn, references object C. Complex types include Arrays, Objects and Functions; these are all objects.

Object.create()

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone and send us a pull request. Return value The target object. Description Properties in the target object will be overwritten by properties in the sources if they have the same key. Later sources' properties will similarly overwrite earlier ones. Therefore it assigns properties versus just copying or defining new properties. This may make it unsuitable for merging new properties into a prototype if the merge sources contain getters. For copying property definitions, including their enumerability, into prototypes and should be used instead. Both and properties are copied. In case of an error, for example if a property is non-writable, a will be raised, and the target object can be changed if any properties are added before error is raised. If the source value is a reference to an object, it only copies that reference value.

If support for older browsers is necessary, or can be used. This is not what we want. Complex types include Arrays, Objects and Functions; these are all objects. In case of an error, for example if a property is non-writable, a will be raised, and the target object can be changed if any properties are added before error is raised. This is for single inheritance, which is all that JavaScript supports. Then again, the actual iteration order is not guaranteed no matter what the order members are added.
