Mastering JavaScript High Performance

JavaScript is a part of all major web browsers and is the most used client-side language with features such as asynchronous communication, controlling the browsers, and altering documents. However, JavaScript performance in the browser is arguably the most important usability issue facing developers. It is sometimes very time-consuming, resulting in a deprecating performance. Studying the JavaScript performance in depth will make developers 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 onto learn about DOM optimization, JavaScript promises, and Web Workers to better break up your large code-base. 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.
