ECMAScript—uses promises for asynchronous operations; Eiffel—through its SCOOP mechanism based on the concepts of Design by Contract; Elixir—dynamic and functional meta-programming aware language running on the Erlang VM. Erlang—uses synchronous or asynchronous message passing with no shared memory
Supporters claim that asynchronous, non-blocking code can be written with async/await that looks almost like traditional synchronous, blocking code. In particular, it has been argued that await is the best way of writing asynchronous code in message-passing programs; in particular, being close to blocking code, readability and the minimal ...
Lazy loading (also known as asynchronous loading) is a technique used in computer programming, especially web design and web development, to defer initialization of an object until it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used.
C#, since .NET Framework 4.5, [22] via the keywords async and await [23] Kotlin, however kotlin.native.concurrent.Future is only usually used when writing Kotlin that is intended to run natively [35] Nim; Oxygene; Oz version 3 [36] Python concurrent.futures, since 3.2, [37] as proposed by the PEP 3148, and Python 3.5 added async and await [38]
Shared memory: Multiple processes are given access to the same block of memory, which creates a shared buffer for the processes to communicate with each other. All POSIX systems, Windows Message passing: Allows multiple programs to communicate using message queues and/or non-OS managed channels. Commonly used in concurrency models.
Alternatives are synchronous method invocation and future objects. [4] An example for an application that may make use of AMI is a web browser that needs to display a web page even before all images are loaded. Since method is a special case of procedure, asynchronous method invocation is a special case of asynchronous procedure call.
Synchronous communication can be built on top of asynchronous communication by using a Synchronizer. For example, the α-Synchronizer works by ensuring that the sender always waits for an acknowledgement message from the receiver. The sender only sends the next message after the acknowledgement has been received.
Ajax (also AJAX / ˈ eɪ dʒ æ k s /; short for "asynchronous JavaScript and XML" [1] [2]) is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications.
