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
