High Performance JavaScript by Nicholas C. ZakasWhile JavaScript engines are getting faster every day, complex logic or heavy DOM manipulation can still lead to sluggish browser performance. Nicholas C. Zakas takes you on a journey into the more subtle areas of JavaScript, providing a deeper understanding of how to create faster and more responsive user interfaces
For many front-end web developers, mastering concepts such as context, closures or callbacks is a major milestone in learning JavaScript. As you start to work with asynchronous events and complicated DOM manipulation, writing JavaScript code can become even more adventurous and quite rewarding. But it is right about this time that you may start to notice sluggish or even non-responsive pages. High Performance JavaScript (Build Faster Web Applications Interfaces), by Nicholas C. Zakas, provides numerous insights that will help you to understand why some of these issues arise and how to prevent them from happening.
With the help of Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney, Mr. Zakas leads the reader through a series of articles that detail advanced techniques for better JavaScript performance. In many cases, it comes down to programming patterns that are not unique to JavaScript, but lend themselves well to this context. But there is also JavaScript-specific advice with regard to cloning nodes, caching references to objects and optimizing expensive operations. Inside these 202 pages is expert advice on how to refactor loops, conditionals and recursion, as well as smarter regular expressions and AJAX. You’ll also find great coverage of the best tools available for improving JavaScript performance.
If you are an intermediate to advanced front-end web developer who is looking to gain a deeper understanding of the JavaScript language, this book is an invaluable resource.
