具體描述
If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more. Yahoo! frontend engineer Nicholas C. Zakas and five other JavaScript experts -- Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney -- demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live. * Identify problem code and use faster alternatives to accomplish the same task * Improve scripts by learning how JavaScript stores and accesses data * Implement JavaScript code so that it doesn't slow down interaction with the DOM * Use optimization techniques to improve runtime performance * Learn ways to ensure the UI is responsive at all times * Achieve faster client-server communication * Use a build system to minify files, and HTTP compression to deliver them to the browser

##讀完瞭，雖然文章末的工具已經很老瞭，不過整體上來說絕絕子。 作者對每個概念進行內存和性能方麵的分析的圖錶令人印象深刻，且講解鞭闢入裏，案例也很棒，贊????????
評分##搭配 jsperf.com 服用。F2E 居傢必備。

評分##即使從 分析 角度來說，也是好書。Analysing & profiling: algorithms, language statements, DOM, render, I/O, parallels, cache, regex & XML etc.
評分##真有用！！
評分##JS基本概念在Zakas另外一本書裏講得全麵得多。工具/工作流程方麵這本2010年的書太過時瞭，而且本來這些就不必成書。
評分##JS本身的執行效率沒什麼好擔心的. 前端性能優化還是 Steve Souders 的兩本書更有價值. 而這些最佳實踐也都已經充分傳播開來瞭.
評分##很棒的書，但因為比較久瞭，裏麵大部分內容已經不再適用瞭。
評分##1、讀這本書拉的戰綫實在夠長，垮瞭2個年。 2、現在瀏覽器版本迭代速度太快，書裏有些數據需要更新，但絲毫不影響這本書的價值。 3、#看彆人傢的工程師#，性能小組，可以做基礎研究。國內大多隻看工程産齣。 4、中英文版本都看瞭。英文原版給5星，翻譯的隻能給2星。
