Dispose pattern. In object-oriented programming, the dispose pattern is a design pattern for resource management. In this pattern, a resource is held by an object, and released by calling a conventional method – usually called close, dispose, free, release depending on the language – which releases any resources the object is holding onto.
Other dynamic languages, such as Ruby and Julia (but not Perl 5 or PHP before version 5.3, [24] which both use reference counting), JavaScript and ECMAScript also tend to use GC. Object-oriented programming languages such as Smalltalk, RPL and Java usually provide integrated garbage collection. Notable exceptions are C++ and Delphi, which have ...
JavaScript has a deprecated Object.observe function that was a more accurate implementation of the observer pattern. [7] 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: [8]
Async/await. Appearance. In computer programming, the async/await pattern is a syntactic feature of many programming languages that allows an asynchronous, non-blocking function to be structured in a way similar to an ordinary synchronous function. It is semantically related to the concept of a coroutine and is often implemented using similar ...
In programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions. Operationally, a closure is a record storing a function [ a ] together with an environment. [ 1 ] The environment is a mapping associating each free variable of ...
In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.An object referenced only by weak references – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable and ...
Website. Standards. ECMAScript (/ ˈɛkməskrɪpt /; ES) [ 1 ] is a standard for scripting languages, including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. [ 2 ] It is standardized by Ecma International in the document ECMA-262.
