Although his material was not used in this edition, his ideas and general outline were quite helpful.
大纲

Javascript is a loosely typed language, which means that variables do not
need to have a type specified. Objects in Javascript map property names to arbitrary property values.

map means 映射  arbitrary means 随意的 任意的

the little-known language Self. 很少知道的一种语言：Self.

Like Perl, Javascript is an interpreted language, and it draws inspiration from Perl in a number of areas, such as its regular-expression and array-handling features.

interpreted language 解释型语言
draw inspiration from 从...中获取灵感
regular-expression 正则表达式
array-handling 数组操作

Javascript is most commonly used in web browsers, and, in that context, the general-purpose core is extended with objects that allow scripts to interact with the user, control the web browser, and alter the document content that appears within the web browsers window.

javascript 在 web 浏览器中应用最为广泛， 在此环境中，通用目的的核心通过对象得到扩展，这些对象允许
脚步与用户交互，控制web 浏览器，以及修改出现在浏览器窗口中的文档内容。

this embedded version of javascript runs scripts embedded within HTML web pages.
这种嵌入式版本的Javascript运行嵌入到HTML web 页面中的脚步。

This is commonly called client-side javascript to emphasize that scripts are run by
the client computer rather than the web server.
他通常称作客户端的javascript，以强调脚本是由客户端计算机运行的而不是由web服务器运行的。

哇 大公鸡又叫了。

The core Javascript language and its built-in datatypes are the subject of international standards,
and compatibility across implementations is very good.
Javascript 的核心语言及其内建的数据类型都符合国际标准，他们跨平台的兼容性都灰常的好。

Part of client-side javascript are formally standardized, other parts are de facto standards, and
other parts are browser-specific extensions.
客户端的javascript一部分是正式化标准的，其他一部分是事实上的标准，而另一部分是特定于浏览器的扩展。

Cross-browser compatibility is often an important concern for client-side javascript programmers.
跨浏览器的兼容性常常是客户端的javascript程序员所关心的一个重要问题。

这是啥东东？推荐几本电子版的JavaScript书来看看吧

我现在看的是 Javascript权威指南第五版 (英文版)。

手边还有个 Javascript权威指南第六版中文版的 呵呵

不是说看完这个东西 别的都是浮云了么

英文版你看得懂？难不成你是传说中的外国人？不可思议

慢慢看 反正有中文版的 也不怕看不明白。

Javascript is the subject of a fair bit of misinformation and confusion.
Before proceeding any further, it is important to debunk two common and persistent myths about the language.

a fair bit of 相当 不少
javascript是一个相当容易被误解和混淆的主题。
在对它进行进一步之前，有必要澄清两点长期存在的对该语言的误解。

One of the most common misconceptions about javascript is that it is a simplified version
of java, the programming language from Sun Microsystems.
对javascript最常见的误解就是认为他是Sun Microsystems公司的程序设计语言Java的简化版本。

Other  than an incomplete syntactic resemblance and the fact that both Java and Javascript
can provide executable content in web browsers, the two languages are entirely unrelated.
但是除了语法上有些相似之处以及都能够提供Web浏览器中的可执行内容之外，这两种语言是完全不相干的。

The similarity of names is purely a marketing ploy by Netscape and Sun(The language was originally
called LiveScript, its name was changed to Javascript at the last minute). However, Javacript can, in
fact, script Jave.
名称上的相似完全是Netscape和Sun的一种营销策略罢了（它最初叫LiveScript,最后才改成Javascript）。然而，实际上，Javascript可以脚本化Java.
