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.

还可以了。jquery那部分貌似有点过时 但是思想挺好的
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5星是推荐，并非指内容....谢谢...
评分相当不错的一本关于Javascript异步编程的书，对比了浏览器端JS引擎和nodejs对JS异步的处理的差别，介绍了目前流行的一些异步JS框架
