javascript奇怪的编码

Question

我越来越奇怪的字符在网页的脚本。这是脚本的一部分

___=~[];___={___:++___,$$$$:(![]+"")[___],__$:++___,$_$_:(![]+"")[___],_$_:++___,$_$$:({}+"")[___],$$_$:(___[___]+"")[___],_$$:++___,$$$_:(!""+"")[___],$__:++___,$_$:++___,$$__:({}+"")[___],$$_:++___,$$$:++___,$___:++___,$__$:++___};___.$_=(___.$_=___+"")[___.$_$]+(___._$=___.$_[___.__$])+(___.$$=(___.$+"")[___.__$])+((!___)+"")[___._$$]+(___.__=___.$_[___.$$_])+(___.$=(!""+"")[___.__$])+(___._=(!""+"")[___._$_])+___.$_[___.$_$]+___.__+___._$+___.$;___.$$=___.$+(!""+"")[___._$$]+___.__+___._+___.$+___.$$;___.$=(___.___)[___.$_][___.$_];___.$(___.$(___.$$+"\""+"\\"+___.__$+___.$$_+___.$$_+___.$_$_+"\\"+___.__$+___.$$_+___._$_+"\\"+___.$__+___.___+___._$+___.$_$$+"\\"+___.__$+___.$_$+___._$_+"\\"+___.$__+___.___+"=\\"+___.$__+___.___+"{\\"+___.$__+___.___+"};\\"+___.__$+___._$_+___._$+___.$_$$+"\\"+___.__$+___.$_$+___._$_+".\\"+___.__$+___.$$_+___._$$+___.$$$_+___.$$__+"\\"+___.__$+___.$$_+___._$_+___.$$$_+___.__+"\\"+___.$__+___.___+"=\\"+___.$__+___.___+"\\\"\\"+___.__$+___.___+___.__$+"\\"+___.__$+___.$_$+___.$$_+"\\"+___.__$+___.$__+___.$$$+___.$$$_+(![]+"")[___._$_]+"\\"+___.__$+___.$_$+___.__$+"\\"+___.__$+___.$_$+___.$$_+___.$_$_+"\\"+___.$__+___.___+"\\"+___. 

这翻译以一种奇怪的方式提醒（“为什么”）。这怎么可能？

Answer 1

这被称为代码混淆，使用utf-8字符，而不是我们的英文字母。变量具有有效的名称，通常有函数调用，会做转换为通过警报输出提供英文文本等
