return type is async.operation, we know it is an asynchronous call, using a special method and so on before it executes. callbackResult = callback(self.result); self.result = callbackResult; if (callbackResult callbackResult instanceof Async.Operation) { 　 innerChain = Async.chain(); 　 while (callbackQueue.length > 0) { 　 　 innerChain.next(callbackQueue.shift()); 　 } 　 innerChain.next(function(result) { 　 　 self.result = result; 　 　 self.state = "c

function as the second argument to promise's then method. Tips Promise represents the final value, which results when the parallel operation is completed Using promise to combine different parallel operations Use promise-mode APIs to avoid data contention Use Select (also known as choose) when required for intentional competitive conditions Extended reading Promise https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Refe

Asynchronous mode is becoming more and more important in web programming, which is not very easy to implement for Web-leading language JavaScript, so many JavaScript libraries (such as jquery and Dojo, AngularJS) Adds an abstraction called promise (the term is called deferred mode). Through these libraries, developers can use the promise pattern in real programmi

then rewrite some of the methods, usually starting with Handle_. Example of Port forwardingIf your program wants to do one thing at a time, multithreading is the quickest and most common way, but there is also a way to be particularly useful when I/O traffic is large. If your operating system supports the Select function, you can let I/O read and write in the background. This module sounds complicated, but there are actually many ways to understand i

Page capturing ajax asynchronous content is not much different from page capturing normal content. Ajax is just an asynchronous http request. the following example shows that the page for capturing ajax asynchronous content is slightly different from the page for capturing common content. Ajax only implements an

promise is a very simple concept, and even if you don't have a chance to use it, chances are that you've learned about it. Promise is a valuable constructor that can help you avoid using nested anonymous methods and assemble asynchronous code in a more readable way. Here we will introduce the 6 simplest features that we would like to help you with. Before we begin our formal presentation, we'd like to look at the

Introduction to problematic asynchronous InterfacesRiple It is the sequence diagram of accessing the IDE Hard Drive Device by using MDMA on the host (PC).

At the outset, it is somewhat difficult to understand the order of the asynchronous program's invocation. For example, in the following program, starting will be printed first, then finished:downloadasync ( " file.txt" , function (file ) { Console.log ( " Finished );}); Console.log ( " Starting ); downloadasync method returns immediately after execution, and it simply registers a callback function f
