以前对黑客很崇拜，黑客的世界无比精彩。最近为了炫耀，想起了这段特殊的代码。

这是一段js代码，把它放到你的控制台里面运行，看看发生了什么？

这段代码来着于这个网站转码得到：http://www.jsfuck.com/

源码：

alert("hello")

　　这是一个黑客奇葩的想法。

　　在黑客行为中，你的js代码可能被关键词检测，于是考虑躲避关键词检测的想法，例如 eval等关键词。

　　1、想了各种方法来规避这个检测。

　　2、把方法写成通用的程序。

　　3、把包含的字符做到极致，最后只剩下 ()+[]!  这六个字符。

这里是它的百科，感兴趣可以去了解下：https://en.wikipedia.org/wiki/JSFuck

用途：

1、脚本注入时防止过滤

2、一定程度加密关键代码（生成代码很长，不适合加密大量代码。只能一定程度上加密，不能依赖）

3、装逼用（我最中意的用途）

结论：转换后本质依然是javascript，通过javascript的一些性质来生成，具体实现可以看这里的代码https://github.com/aemkei/jsfuck
