JavaScript: The Good Parts（影印版）

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扩展的和高效的代码。
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。在《JavaScript：The Good Parts》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
使用《JavaScript：The Good Parts》一书, 你会发现一个美丽、优雅、轻量级和具有很强表达能力的语言，让你创造有效的代码，无论你正在管理对象库，还是只是试着让Ajax快速运行。如果你为Web开发站点或者应用程序，那么这本书是绝对必需的。
Douglas Crockford是雅虎的高级JavaScript架构师，他以发明和维护JSON（JavaScript对象注释）而闻名。他经常在JavaScript高级主题的会议上发言，也是ECMAScript委员会的成员。

The animal on the cover of JavaScript: The Good Parts is a Plain Tiger butterfly
(Danaus chrysippus).Outside of Asia, the insect is also known as the African
Monarch.It is a medium-size butterfly characterized by bright orange wings with six
black spots and alternating black-and-white stripes.
Its striking looks have been noted for millennia by scientists and artists.The writer
Vladimir Nabokov—who was also a noted lepidopterist—had admiring words for
the butterfly in an otherwise scathing New York Times book review of Alice Ford’s
Audubon’s Butterflies, Moths, and Other Studies (The Studio Publications).In the
book, Ford labels drawings made previous to and during Audubon’s time in the 19th
century as “scientifi-cally [sic] unsophisticated.”
In response to Ford, Nabokov writes, “The unsophistication is all her own.She
might have looked up John Abbot’s prodigious representations of North American
lepidoptera, 1797, or the splendid plates of 18th- and early-19th-century German
lepidopterists.She might have traveled back some 33 centuries to the times of Tuthmosis
IV or Amenophis III and, instead of the obvious scarab, found there frescoes
with a marvelous Egyptian butterfly (subtly combining the pattern of our Painted
Lady and the body of an African ally of the Monarch).”
While the Plain Tiger’s beauty is part of its charm, its looks can also be deadly.
During its larval stages, the butterfly ingests alkaloids that are poisonous to birds—
its main predator—which are often attracted to the insect’s markings.After ingesting
the Plain Tiger, a bird will vomit repeatedly—occasionally fatally.If the bird lives, it
will let other birds know to avoid the insect, which can also be recognized by its
leisurely, meandering pattern of flying low to the earth.
