High Performance Javascript provides the reader with numerous techniques and strategies to overcome performance issues during development. It guides the reader on ways to improve execution time, interacting with the Document Object Model (DOM), page life cycle, downloading and a lot more. Summary Of The Book JavaScript is an interpreted programming language which when used as part of web browsers enables client-side scripts to interact with the user in addition to controlling the web browser. It supports functional and object-oriented programming styles. JavaScript is popular in game development, server-side programming and the development of desktop applications. Outside of web pages, it is also used in PDF documents, desktop widgets and site-specific browsers. A number of interactive and quick-responding web applications rely on JavaScript to provide a superior web-experience to their visitors. The flipside though is that many a time the large number of JavaScript code lines can considerably slow down the applications or websites. High Performance Javascript is just the book that arms the reader with enough tips and techniques to eliminate such performance bottlenecks at the time of development. It teaches the reader about the best possible way to load code on a page in addition to offering useful tips that enable the running of JavaScript both quickly and efficiently. It is also packed with tried and tested practices that help build and deploy files to a production environment, and lists tools that can help troubleshoot problems quickly on live sites. Some of the other topics in High Performance Javascript that a reader is bound to find useful are to do with the identification of problem code and the usage of quicker alternatives to accomplish a task, optimize scripts by understanding how JavaScript stores and accesses data, use techniques that help improve performance during runtime, achieving a faster client-server interaction, tips to ensure that the user interface is responsive at all times; implement JavaScript code in a manner that avoids slowing down of interaction with the DOM; and how to use a build system that minimizes the file sizes and HTTP compression while delivering them to the web browser.
