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]
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.
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 ...
C# implements closure blocks by means of the using statement. The using statement accepts an expression which results in an object implementing IDisposable, and the compiler generates code that guarantees the object's disposal when the scope of the using -statement is exited. The using statement is syntactic sugar.
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 ...
