Late bindingLate binding is the act or mechanism of binding two software entities at runtime as opposed to early binding which occurs before the program starts – such as design or build times. The implementation of late binding differs by context. The term dynamic binding is sometimes used for the same concept, but is more commonly refers to dynamic scope. HistoryThe term "late binding" dates back to at least the 1960s, where it can be found in Communications of the ACM.Static dispatchIn computing, static dispatch is a form of polymorphism fully resolved during compile time. It is a form of method dispatch, which describes how a language or environment will select which implementation of a method or function to use. Examples are templates in C++, and generic programming in Fortran and other languages, in conjunction with function overloading (including operator overloading).
Objective-CGeneral-purpose, object-oriented programming languageObjective-C is a high-levelgeneral-purpose, object-orientedprogramming language that adds Smalltalk-style message passing (messaging) to the C programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEPoperating system.
Python (programming language)General-purpose programming languagePython is a high-level, general-purpose programming language that emphasizes code readability, simplicity, and ease-of-writing with the use of significant indentation, an extensive ("batteries-included") standard library, and garbage collection. Python supports multiple programming paradigms but with an emphasis on object-oriented programming and dynamic typing.Method (computer programming)A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message. An object consists of state data and behavior; these compose an interface, which specifies how the object may be used. A method is a behavior of an object parametrized by a user. Data is represented as properties of the object, and behaviors are represented as methods.
JavaScriptJavaScript (JS) is a programming language and core technology of the Web, alongside HTML and CSS. Created by Brendan Eich in 1995, it is maintained by Ecma International's TC39 technical committee, with related Web APIs maintained by W3C and WHATWG.Message passingIn computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer. The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code. Message passing differs from conventional programming where a process, subroutine, or function is directly invoked by name.
SmalltalkSmalltalk is a purely object-orientedprogramming language that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learning Research Group (LRG) scientists, including Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Diana Merry, and Scott Wallace.Polymorphism (computer science)In programming language theory and type theory, polymorphism allows a value or variable to have more than one type and allows a given operation to be performed on values of more than one type. In object-oriented programming, polymorphism is the provision of one interface to entities of different data types. The concept is borrowed from a principle in biology in which an organism or species can have many different forms or stages.Name bindingIn computer programming, name binding is the association of a data or code entity with an identifier. An identifier bound to an entity is said to reference that entity. A machine language has no built-in notion of identifiers, but name-entity binding as a service and notation for the programmer is implemented by higher-level programming languages.
Object-oriented programmingObject-oriented programming (OOP) is a programming paradigm based on objects – software entities that encapsulatedata and function(s). An OOP computer program consists of objects that interact with one another. An OOP language is one that provides object-oriented programming features, but as the set of features that contribute to OOP is contested, classifying a language as OOP – and the degree to which it supports OOP – is debatable.Compile timeIn computing, compile time is the period of time when a compiler processes source code into other code that is more readily executable – typically object code or byte code. Compile time is a phase in the operational life cycle of a program as it transitions from development to execution. The length of time it takes to compile is usually referred to as compilation time although compile time might also be used. Compile time can be subdivided by the phases of a compiler.
