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

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
评分也就最后一章还行,前面几章没一点有用的东西。

评分专题讲解异步Javascript实现,不过关于Promises的主题只是介绍了用法(基于jQuery和Node.js),拜托,我想看看这些API的实现细节好不好……看样子只能另谋资料了。不过整体而言,还算是给JSer开眼界的好手册,不厚(不是特指某个敏感人物哦,嘿嘿),含金量挺高的,推荐给中、高级前端开发人员。
评分薄薄一本书,举几个实用的例子,反复阐述几个概念,很好。
