  2. Function object - Wikipedia

    en.wikipedia.org/wiki/Function_object

    A closure-constructing operator creates a function object from a part of the program: the part of code given as an argument to the operator is part of the function, and so is the lexical environment: the bindings of the lexically visible variables are captured and stored in the function object, which is more commonly called a closure.

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    The following are notable software design patterns for OOP objects. [59] Function object: with a single method (in C++, the function operator, operator()) it acts much like a function; Immutable object: does not change state after creation; First-class object: can be used without restriction; Container object: contains other objects

  4. Object model - Wikipedia

    en.wikipedia.org/wiki/Object_model

    For example, the Document Object Model (DOM) is a collection of objects that represent a page in a web browser, used by script programs to examine and dynamically change the page. There is a Microsoft Excel object model [1] for controlling Microsoft Excel from another program, and the ASCOM Telescope Driver is an object model for controlling an ...

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    C# is intended to be suitable for writing applications for both hosted and embedded systems, ranging from the very large that use sophisticated operating systems, down to the very small having dedicated functions. Although C# applications are intended to be economical with regard to memory and processing power requirements, the language was not ...

  6. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes.

  7. JavaScript - Wikipedia

    en.wikipedia.org/wiki/JavaScript

    Unlike in many object-oriented languages, in JavaScript there is no distinction between a function definition and a method definition. Rather, the distinction occurs during function calling. When a function is called as a method of an object, the function's local this keyword is bound to that object for that invocation.

  8. Dynamic dispatch - Wikipedia

    en.wikipedia.org/wiki/Dynamic_dispatch

    In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time.It is commonly employed in, and considered a prime characteristic of, object-oriented programming (OOP) languages and systems.

  9. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    JavaScript has a deprecated Object.observe function that was a more accurate implementation of the observer pattern. [10] This would fire events upon change to the observed object. Without the deprecated Object.observe function, the pattern may be implemented with more explicit code: [11]
