Differential Inheritance
Differential inheritance is a common Inheritance (object-oriented programming), inheritance model used by Prototype-based programming, prototype-based programming languages such as JavaScript, Io (programming language), Io and NewtonScript. It operates on the principle that most objects are derived from other, more general objects, and only differ in a few small aspects; while usually maintaining a list of pointers internally to other objects which the object differs from. An analogy To think of differential inheritance, you think in terms of what is different. So for instance, when trying to describe to someone how Dumbo looks, you could tell them in terms of elephants: ''Think of an elephant. Now Dumbo is a lot shorter, has big ears, no tusks, a little pink bow and can fly.'' Using this method, you don't need to go on and on about what makes up an elephant, you only need to describe the differences; anything not explicitly different can be safely assumed to be the same.

Inheritance (object-oriented Programming)
In object-oriented programming, inheritance is the mechanism of basing an Object (computer science), object or Class (computer programming), class upon another object (Prototype-based programming, prototype-based inheritance) or class (Class-based programming, class-based inheritance), retaining similar implementation. Also defined as deriving new classes (#Subclasses and superclasses, sub classes) from existing ones such as super class or Fragile base class, base class and then forming them into a hierarchy of classes. In most class-based object-oriented languages like C++, an object created through inheritance, a "child object", acquires all the properties and behaviors of the "parent object", with the exception of: Constructor (object-oriented programming), constructors, destructors, operator overloading, overloaded operators and friend functions of the base class. Inheritance allows programmers to create classes that are built upon existing classes, to specify a new implementat ...
