功能：Javascript代码压缩与混淆
点评：Javascript Obfuscator v4.0 比JS Min 和YUI Compressor 的压缩率要高，并且混淆效果更好，可以很方便的人工控制哪些名称混淆哪些不混淆，界面也非常的美观。
美中不足：是一款共享软件，试用版会有一些功能限制。
特性：
- 能自动处理html文件中的javascript标签，html页面文件引用的关联.js文件。就像处理单独的.js文件一样方便
- 移除注释与空白，减小文件尺寸，使载入时间减到最少。（注：这没什么，最基本的）
- 将代码压缩为长长的一行
- 必需的时候自动添加分号结束符
- 创建函数名与变量名的列表
- 根据用户的设定，生成难以读懂的或指定修改函数名和变量名
- 同时也支持命令行

- remove comments and white spaces, reducing the file size and minimizing the loading time
- pack the code as a long line
- add finishing ";" when appropriate
- create a list of function and variable names
- generate new non-understandable names and rename functions and variables depending on user settings
- work with command line
