好用的js压缩工具esc
js压缩在高访问量的项目中是很有必要的。以前在网络上找了很多软件，都有这样那样的一些问题，有句话说得好"js压缩没有权威"。但esc确实是一款很不错的工具。
使用方法:
ESC(ECMAScript cruncher)这个工具只能在Windows下使用,ESC.wsf提供5种压缩级别，从0到4：
Level 0 :: No compression 不对JS文件进行压缩
Level 1 :: Comment removal 移除JS文件中的注释
Level 2 :: Whitespace removal 移除JS文件中的注释及空行（一般选择此级别就足够了）
Level 3 :: Newline removal 移除JS文件中的注释，将所有代码合并为一行
Level 4 :: Variable substitution 提供最新的压缩率，移除JS文件中的注释，将所有代码合并为一行，并且修改JS文件中的变量名
在WINDOWS命令行下执行
cscript ESC.wsf -ow 压缩后文件.js 压缩前文件.js 将压缩前的js文件按照压缩级别2来压缩（ESC.wsf默认压缩级别为2）
cscript ESC.wsf -l 3 -ow 压缩后文件.js Common.js 将压缩前的js文件按照压缩级别3来压缩为"压缩后文件.js"
需要注意的是，ESC.wsf压缩级别4会把变量名修改，如果你的js中用到了全局变量或者类的话，就不能使用该压缩级别了，否则其它使用你的js的文件可能会无法正常运行。
