    en.wikipedia.org/wiki/Factory_(object-oriented...

    In object-oriented programming, a factory is an object for creating other objects; formally, it is a function or method that returns objects of a varying prototype or class [1] from some method call, which is assumed to be new. [a] More broadly, a subroutine that returns a new object may be referred to as a factory, as in factory method or ...

    en.wikipedia.org/wiki/Object-oriented_programming

    External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable. A program may create many instances of objects as it runs, which operate independently.

  7. Fluent interface - Wikipedia

    en.wikipedia.org/wiki/Fluent_interface

    In Python, returning self in the instance method is one way to implement the fluent pattern. It is however discouraged by the language’s creator, Guido van Rossum, [3] and therefore considered unpythonic (not idiomatic) for operations that do not return new values. Van Rossum provides string processing operations as example where he sees the ...

  8. Prototype JavaScript Framework - Wikipedia

    en.wikipedia.org/wiki/Prototype_JavaScript_Framework

    In JavaScript, object creation is prototype-based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function. The Prototype framework is not to be confused with this language feature.
