Prototype also provides library functions to support classes and class-based objects. [2] 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 ...
On the mainframe operating system MUSIC/SP, if one asks for the file name "X", one is making an unqualified reference either to the file X in the user's library, or to the file X in the common library if the user does not have a file named X and one does exist in the common library. If, however, one were to refer to "*COM:X" one is using a ...
In object-oriented programming, a god object (sometimes also called an omniscient or all-knowing object) is an object that references a large number of distinct types, has too many unrelated or uncategorized methods, or some combination of both. [1] The god object is an example of an anti-pattern and a code smell. [2]
In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...

A reference to an instance of a class may actually be referring to one of its subclasses. The actual class of the object being referenced is impossible to predict at compile-time. A uniform interface is used to invoke the member functions of objects of a number of different classes.
When the COM class factory tries to instantiate a class, the activation context is first checked to see if an implementation for the CLSID can be found. Only if the lookup fails, the registry is scanned. [16] A COM object can be created without type library information; with only a path to the DLL file and CLSID.
A JavaScript library is a library of pre-written JavaScript code that allows for easier development of JavaScript-based applications, [1] especially for AJAX and other web-centric technologies. [2] They can be included in a website by embedding it directly in the HTML via a script tag.
