Master the art of building, deploying, and optimizing faster web applications with JavaScript If you are a JavaScript developer with some experience in development and want to increase the performance of JavaScript projects by building faster web apps, then this book is for you. You should know the basic concepts of JavaScript. Studying JavaScript performance in depth will make you capable of tackling the complex and important tasks required to solve performance issues. In this book, you'll learn when and why to use an IDE over a common text editor. Packed with examples, you'll also learn how to create a build system to test and deploy your JavaScript project by optimizing the code. Next, you will move on to learn about DOM optimization, JavaScript promises, and web workers to better break up your large codebase. You will also learn about JavaScript performance on mobile platforms such as iOS and Android and how to deploy your JavaScript project to a device. Finally, by the end of the book, you'll be able to pinpoint JavaScript performance problems using appropriate tools, provide optimization techniques, and provide tools to develop fast applications with JavaScript.
A bit dated, but fundamentally sound and covers and incredible variety of sub-topics related to performance/optimization of JavaScript. I tip my hat to the author for spending a couple chapters diving into browser performance profiling tools against the PacktPub website; that slow, monolithic, beast of a site deserves a bit of scrutiny (and probably proves what I've suspected for awhile that PacktPub reviewers don't really read any of the books they're reviewing :)
