What You Will Learn Understand exactly how JavaScript works in a web browser environment and how these mechanisms power our event-driven JavaScript code Use promises to turn complex synchronization scenarios into readable and maintainable code Compute values lazily and avoid unnecessary memory allocations using generators Write concurrent code that doesn't feel like concurrent code by abstracting away boilerplate chores Leverage true hardware parallelism with web workers to get better performance Get to grips with the NodeJS model of concurrency and learn why it's good for I/O-intensive web applications 《JavaScript:The Good Parts(影印版)》一书中，Crockford深度分析了一堆好的意图和盲目的错误，为你提供了所有JavaScript的地道优良部分的细节，包括：·语法·继承·方法；·对象·数组·风格；·函数·正则表达式·美丽的特性大多数编程语言包含优良和拙劣的部件，但对JavaScript而言后者的比重较大，因为它在匆忙中开发和发布，还没能够得到精炼。这本权威的书剔除了大多数可怕的JavaScript特性，展现了JavaScript的另一部分，这一部分比JavaScript语言作为一个整体更加稳定、更具有可读性以及可维护性——可以用这个部分创建真正可展的合高效的代码。, 作者Douglas Crockford(他被很多开发社区认为是JavaScript专家)提出了足够多的好想法，让JavaScript成为一个杰出的面向对象编程语言。不幸的是，这些好想法(比如函数、弱类型、动态对象和表达能力很强的对象文字注释)被掺杂了些坏想法(比如基于全局变量的编程模型)。, 当Java Applet陨落的时候，JavaScript成为了Web编程的缺省语言，但它的流行程度跟它作为一个编程语言的质量完全没有关系。
