JSFuck 可以让你只用 6 个字符 []()! 来编写 JavaScript 程序。例如你想用 JSFuck 来实现 alert(1) 代码如下：[][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]][([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[! [] ! [] ! []]]] ([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[! [] ! [] ! [] ! [] ! [] ! []]]] ([][[]] [])[ [[ ! []]]] (![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[ ! []]]] ([][[]] [])[ [[ []]]] ([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ []]]] ([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[! [] ! [] ! [] ! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]]((![] [])[ [[ ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]] (!![] [])[ [[ []]]] ([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[ ! []]] [[! [] ! [] ! [] ! [] ! []]]] [ ! []] ([][(![] [])[ [[ []]]] ([][[]] [])[ [[! [] ! [] ! [] ! [] ! []]]] (![] [])[ [[! [] ! []]]] (!![] [])[ [[ []]]] (!![] [])[ [[! [] ! [] ! []]]] (!![] [])[ [[ ! []]]]] [])[ [[ ! []]] [[! [] ! [] ! [] ! [] ! [] ! []]]])()其他一些基本的表达：false => ![]true => !![]undefined => [][[]]NaN => [![]]0 => []1 => ! []2 => ! [] ! []10 => [ ! []] [ []]Array => []Number => []String => [] []Boolean => ![]Function => []["filter"]eval => []["filter"]["constructor"]( CODE )()window => []["filter"]["constructor"]("return this")()
