Answer 3

($=[$=[]][(__=!$+$)[_=-~-~-~$]+({}+$)[_/_]+ ($$=($_=!''+$)[_/_]+$_[+$])])()[__[_/_]+__ [_+~$]+$_[_]+$$](_/_); (
  $=[$=[]]                                                // $ = []
    [
        (__= !$ + $)                                   // __ = "false"
            [_=-~-~-~$]                                // _ = 3  
                                                              // (__)[3] = "s"
                +
        ({} + $)                                           // ({} + $) = [object Object]
            [_/_]                                           // _/_ = 1
                +                                            // ([object Object])[1] = "o"    
        ($$ =   //
                ($_=!'' + $)                            // !''+ $ = "true"  ;  $_ = "true"
                        [_/_]                              // _/_ = 1;  
                                                             // $_[1] = "r"
                    +  
                $_[+$]                                   // +$ = 0;  $_[0] = "t"
        )                                                   // $$= "rt"
    ]                                                       // ["sort"] 
                                                            // []["sort"] = [].sort = function sort() { [native code] }
                                                            // $ = []["sort"]
)()                                                        // ($)() = [object Window]
[
    __[_/_]                                            // __ = "false";  
                                                           // __[1] = "a"
        +
    __ [_+~$]                                       //_ = 3;  ~$ = -1;  _ + ~$ = 2
                                                          // __[2] = "l"
        +
    $_[_]                                             // $_ = "true" ; _ = 3;
                                                         // $_[3] = "e"
        +
     $$                                                // $$ = "rt"
](_/_);                                               // _ / _ = 1
                                                        // window["alert"](1)這裏需要注意的幾點:1. javascript 裏面 $, _ 均可以作爲變量名2. 函數還可以這樣調用: 比如  [1,2,4,1,9,1].sort()  可以寫成 [1,2,4,1,9,1]["sort"]();3. ~ 對數字按位取反4.  javascript 中在對不同類型的變量 使用 + 時候的規則5.  最後一個針對某些native code寫的方法，執行會返回 window對象， 比如var s = [].sort ; t=s();  則  t 是 window
