jsfuck编码

它常用字符是8个：< > + – . , [ ] 。 JSFuck 是一种基于 JavaScript 原子部分的晦涩的编程风格，它只有 6 种字符：[]()!+ ，也可以来编写程序并执行。并且它还不依赖浏览器，所以还能在 Node.js 上运行。

基本规则

Basics

false => ![]
true => !![]
undefined => [][[]]
NaN => +[![]]
0 => +[]
1 => +!+[]
2 => !+[]+!+[]
10 => [+!+[]]+[+[]]
Array => []
Number => +[]
String => []+[]
Boolean => ![]
Function => []["filter"]
eval => []["filter"]["constructor"]( CODE )()
window => []["filter"]["constructor"]("return this")()

可以放在html文件的js部分里，然后直接运行
