具体描述

"Async JavaScript is the first full book I've seen dedicated to a key topic in JavaScript development today: how to deal with concurrency and concurrent tasks without going crazy! For the sake of your sanity, check this out."

—Peter Cooper, creator of JavaScript Weekly

JavaScript is a single-threaded language living in a multimedia, multi-tasking, multi-core world. Even experienced JavaScripters sometimes find themselves overwhelmed as complex apps grow into a tangled web of callbacks.

With Async JavaScript, you'll learn about:

•Event scheduling

•The PubSub pattern

•Promises and Deferred objects

•Flow control with Async.js

•Recipes for common async scenarios

•Multi-threading with Web Workers

•AltJS languages

and more, with examples tailored to jQuery and Node.js.

作者简介

Trevor is a freelance web developer, author, and speaker living in Cambridge, MA. His first book, CoffeeScript: Accelerated JavaScript Development, was published by PragProg.

薄薄一本书,举几个实用的例子,反复阐述几个概念,很好。

异步,现在想想,其实也不是什么特别的东西,该抢占的时候抢占,该分支的时候分支,该顺序的时候顺序,不管callback还是promise,代码再优雅,还是要从设计出发呀
