What's the best approach for developing an application with JavaScript? This book helps you answer that question with numerous JavaScript coding patterns and best practices. If you're an experienced developer looking to solve problems related to objects, functions, inheritance, and other language-specific categories, the abstractions and code templates in this guide are ideal -- whether you're writing a client-side, server-side, or desktop application with JavaScript. Written by JavaScript expert Stoyan Stefanov -- Senior Yahoo! Technical and architect of YSlow 2.0, the web page performance optimization tool -- JavaScript Patterns includes practical advice for implementing each pattern discussed, along with several hands-on examples. You'll also learn about anti-patterns: common programming approaches that cause more problems than they solve.* Explore useful habits for writing high-quality JavaScript code, such as avoiding globals, using single var declarations, and more * Learn why literal notation patterns are simpler alternatives to constructor functions * Discover different ways to define a function in JavaScript * Create objects that go beyond the basic patterns of using object literals and constructor functions * Learn the options available for code reuse and inheritance in JavaScript * Study sample JavaScript approaches to common design patterns such as Singleton, Factory, Decorator, and more * Examine patterns that apply specifically to the client-side browser environment

If you want to significantly expand your web development skills beyond PHP, this practical, hands-on book teaches you ECMAScript - the core JavaScript language - from the ground up.

Learn everything you need to know about object-oriented JavaScript with this comprehensive guide. Enter the world of cutting-edge development!Key Features[*] This book has been updated to cover all the new object-oriented features introduced in ECMAScript 6[*] It makes object-oriented programming accessible and understandable to web developers[*] Write better and more maintainable JavaScript code while exploring interactive examples that can be used in your own scriptsBook DescriptionJavaScript is an object-oriented programming language that is used for website development. Web pages developed today currently follow a paradigm that has three clearly distinguishable parts: content (HTML), presentation (CSS), and behavior (JavaScript). JavaScript is one important pillar in this paradigm, and is responsible for the running of the web pages.This book will take your JavaScript skills to a new level of sophistication and get you prepared for your journey through professional web development.
