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
用戶評價
##現在是2013年，剛花瞭幾個小時把這本書通讀瞭一遍。書很薄，內容很直白，讀起來飛快。可以想像就2010年的時間點來說這本書裏很多建議挺靠譜的。但如果它今天再版的話，很多內容恐怕都要修正瞭，特彆是關於JavaScript核心語言性能的部分。而且總覺得這書有些細節上技術術語用詞不準確⋯不過不影響大的主題，問題不大。
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##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##真有用！！
