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 ...
Under Unix, the "everything is a file" paradigm naturally leads to a file-based event loop. Reading from and writing to files, inter-process communication, network communication, and device control are all achieved using file I/O, with the target identified by a file descriptor. The select and poll system calls allow a set of file descriptors ...
By examining the return parameters of the select call, the loop finds out which file descriptor has changed and executes the appropriate code. Often, for ease of use, the select loop is implemented as an event loop , perhaps using callback functions ; the situation lends itself particularly well to event-driven programming .
synchronous code execution (SwingUtilities.invokeAndWait(Runnable) or EventQueue.invokeAndWait(Runnable)) and asynchronous code execution (SwingUtilities.invokeLater(Runnable) or EventQueue.invokeLater(Runnable)) from the event dispatching thread.
Many dynamic languages, such as JavaScript, Lua, Python, Perl [1] [2] and PHP, allow a function object to be passed. CLI languages such as C# and VB.NET provide a type-safe encapsulating function reference known as delegate. Events and event handlers, as used in .NET languages, provide for callbacks.
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.
