High Performance JavaScript

by Nicholas C. Zakas

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

[Illia Olenchenko · Rating 5 out of 5]

Книга отличная и действительно дает понять насколько зависят оптимизации от типа ошибок и как их лучше применить. Настоящим открытием стал пример Устройства Дафа, который действительно на больших кол-вах операций ускоряет процесс выполнения по сравнению с циклов в 2-3 раза. Так же очень интересные последние 2 главы об инструментах и способах построения проектов. Отлична написана часть про регулярные выражения. Рекомендую.
