本书是JavaScript超级畅销书的新版。ECMAScript 5 和HTML5在标准之争中双双胜出,使大量专有实现和客户端扩展正式进入规范,同时也为JavaScript增添了很多适应未来发展的新特性。本书这一版除增加5 章全新内容外,其他章节也有较大幅度的增补和修订,新内容篇幅约占三分之一。全书从JavaScript语言实现的各个组成部分——语言核心、DOM、BOM、事件模型讲起,深入浅出地探讨了面向对象编程、Ajax 与Comet服务器端通信,HTML5表单、媒体、Canvas(包括WebGL)及Web Workers、地理定位、跨文档传递消息、客户端存储(包括IndexedDB)等新API,还介绍了离线应用和与维护、性能、部署相关的最佳开发实践。本书附录展望了未来的API和ECMAScript Harmony规范。 本书适合有一定编程经验的Web应用开发人员阅读,也可作为高校及社会实用技术培训相关专业课程的教材。
JavaScript面向对象精要
关注面向对象的原理和ES5对象新特性,目的是帮助那些已经熟知面向对象编程的读者掌握这些概念是如何在JavaScript中工作的。 内容简洁而精妙。全书共6章,分别深入探讨了原始类型和引用类型、函数、对象、构造函数和原型对象、继承和对象模式等主题和特性。在本书中,你将学到JavaScript独特的面向对象的编程方式;抛弃类的概念和基于类的继承,学习基于原型的继承和构造函数。你将学会如何创建对象、定义自己的类型、使用继承以及其他各种操作来充分使用对象。总而言之,你将学到JavaScript语言并进行专业编程所需熟知的一切。 适合熟悉面向对象编程的概念并希望将其应用于JavaScript的开发者阅读,也适合JavaScript新手学习参考。
一天理解JavaScriptPromise
自从2015年被引入JavaScript以来,Promise已经成为这门语言的重要组成部分。所有新的异步应用程序接口都是基于Promise构建的。正因为如此,深入理解Promise的原理是JavaScript开发人员的进阶必修课,也是所有JavaScript编程工作的重中之重。本书共有5章,篇幅短小精悍,代码清晰易懂。每一章从不同的方面展示了使用Promise的关键点和难点。随书附赠的Promise速查表有助于随用随查。读完本书,你将能在自己的项目中游刃有余地进行异步编程。现在就跟随著名JavaScript程序员尼古拉斯• C. 扎卡斯,开启JavaScript Promise之旅吧! 编辑推荐 JavaScript Promise,让异步编程简单起来! Promise是JavaScript异步编程的基石。掌握它,你将不再被“回调地狱”所困扰,也不再为异步代码的复杂性而苦恼。深入理解Promise是编写安全、可扩展、高性能JavaScript应用程序的关键。现在就翻开本书,踏上Promise学习之旅,释放你的异步编程潜力吧!

Nicholas C. Zakas worked with the Web for over a decade. He has worked on corporate intranet applications used by some of the largest companies in the world and large-scale consumer websites such as MyYahoo! and the Yahoo! homepage. He regularly gives talks at companies and conferences regarding front-end best practices and new technology.

Maintainable JavaScript
When you're writing code alone, you have a lot of leeway. But when you start writing code as part of a team, you need to think harder about the decisions you make. This book will help you do that. When you write code in a team setting, will other developers be able to understand what you did? Did you organize your code in such a way that it's easy to adapt and extend? Will your code survive once you're gone? Maintainable JavaScript doesn't just recommend a set of guidelines, it examines guidelines being used and recommended by others in the industry, so you get a feel for what's common in well-run JavaScript projects. Save a copy of this book now. It's the only resource that focus solely on JavaScript conventions.
Principles of Object-Oriented JavaScript
If you've used a more traditional object-oriented language, such as C++ or Java, JavaScript probably doesn't seem object-oriented at all. It has no concept of classes, and you don't even need to define any objects in order to write code. But don't be fooled—JavaScript is an incredibly powerful and expressive object-oriented language that puts many design decisions right into your hands. In The Principles of Object-Oriented JavaScript, Nicholas C. Zakas thoroughly explores JavaScript's object-oriented nature, revealing the language's unique implementation of inheritance and other key characteristics. You'll learn: The difference between primitive and reference values What makes JavaScript functions so unique The various ways to create objects How to define your own constructors How to work with and understand prototypes Inheritance patterns for types and objects The Principles of Object-Oriented JavaScript will leave even experienced developers with a deeper understanding of JavaScript. Unlock the secrets behind how objects work in JavaScript so you can write clearer, more flexible, and more efficient code.
High Performance JavaScript
If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more. Yahoo! frontend engineer Nicholas C. Zakas and five other JavaScript experts -- Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney -- demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live. * Identify problem code and use faster alternatives to accomplish the same task * Improve scripts by learning how JavaScript stores and accesses data * Implement JavaScript code so that it doesn't slow down interaction with the DOM * Use optimization techniques to improve runtime performance * Learn ways to ensure the UI is responsive at all times * Achieve faster client-server communication * Use a build system to minify files, and HTTP compression to deliver them to the browser
