   Object lifecycle[edit] In class-based programming, an object is created as an instance of a class; is a class instance. A client creates an object via a constructor, and destroys the object via a destructor. An abstract class cannot be instantiated. In prototype-based programming, instantiation involves copying (cloning) a prototype instance.
