JavaScript added support for async/await in 2017 as part of ECMAScript 2017 JavaScript edition. Rust added support for async/await with version 1.39.0 in 2019 using the async keyword and the .await postfix operator, both introduced in the 2018 edition of the language.
Synchronization is designed to be cooperative, demanding that every thread follow the synchronization mechanism before accessing protected resources for consistent results. Locking, signaling, lightweight synchronization types, spinwait and interlocked operations are mechanisms related to synchronization in .NET." [11]
Asynchrony, in computer programming, refers to the occurrence of events independent of the main program flow and ways to deal with such events. These may be "outside" events such as the arrival of signals, or actions instigated by a program that take place concurrently with program execution, without the program hanging to wait for results.

The need for synchronization [ edit ] Whenever an electronic device transmits digital (and sometimes analogue) data to another, there must be a certain rhythm established between the two devices, i.e., the receiving device must have some way of, within the context of the fluctuating signal that it's receiving, determining where each unit of ...
Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time . Systems that operate with all parts in synchrony are said to be synchronous or in sync —and those that are not are asynchronous .
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.
In computer science, an event (also called event semaphore) is a type of synchronization mechanism that is used to indicate to waiting processes when a particular condition has become true. An event is an abstract data type with a boolean state and the following operations:
Futures are a particular case of the synchronization primitive "events," which can be completed only once. In general, events can be reset to initial empty state and, thus, completed as many times as desired. [11] An I-var (as in the language Id) is a future with blocking semantics as defined above.
