群里的题目:
void function () { //abcd do break ; while ( typeof delete this ); for ( var a;;) if ( true ) with ( null ) try {} catch (a){}finally{} else throw new 1; switch (1 in 1 instanceof 1) { case false : default : } return ; }; |
谢谢@闹闹爷的提醒,搞了个改进版
new function () { do break ; while ( typeof delete this ); for ( var a;void 0;) continue if ( null ) with (0) try { switch (1 in 1 instanceof 1) { case false : default : throw true } } catch (a){}finally{} else return // console.log("去掉注释可以运行到这里") }; |
