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.
