這個東西也不是新鮮玩意了，很久之前就見過，但是一看到那一大坨代碼，實在是提不起一點研究的興趣。無奈今天碰到這樣一道題目，只好決定深入研究一下。
關於上面的題目，有必要多說幾句。實際上題目並沒有要求一定只有[]()+!這六個字符，要求會寬松不少，不過題目描述中並沒有說明的很清楚。而且運行環境是node，這樣導致並沒有window，history，document這些對象。更沒有window.atob();和window.atob();這兩個函數。總之那道題與我這篇文章並沒有多大關系。不過在通過題目之後，就可以看到別人的解決辦法。果然有高人只用到6種字符就解決問題了。我雖然通過了，但是用到了其它函數，然後我就開始研究別人的代碼了。下面就是我的收獲。
最重要的就是得到任意的數字
+[]=0;
+![]=0;
+!![]=1;
+!+[]=1;
[]+[]="";
[]-[]=0;
[]+{}="[object Object]";
[]-{}=NaN;
{}+{}=NaN; //浏覽器中是NaN，但是node環境中則是"[object Object][object Object]"
{}-{}=NaN;
{}+[]=0;
{}-[]=-0;
得到1之後就可以得到任意數字了
!+[]+!+[]+!+[]+!+[]=4 !![]+!![]+!![]+!![]=4 //我覺得這種形式更直觀些
有些人可能會問123這麼大的數字怎麼辦，難道要寫123個。這裡有個技巧：
!+[]+!+[]+!+[]+!+[]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]]="48" +(!+[]+!+[]+!+[]+!+[]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]])=48 +!![]+[!![]+!![]]+[!![]+!![]+!![]]="123" +(+!![]+[!![]+!![]]+[!![]+!![]+!![]])=123
上面已經得到所有數字了，接下來想辦法得到所有字符。
首先想到的就是如果我有一個字符串s="abcdefg";那麼s[0]="a";s[1]="b";就可以得到很多字符了。不過我們必須先得到一個字符串才行。
比較容易想到的幾個字符串如下：
!![]+[]="true";
![]+[]="false";
[]+{}="[object Object]";
!![]/[]+[]="Infinity";
{}-{}+[]="NaN";
[]-{}+[]="NaN";
[][[]]+[]="undefined";
上面的字符串通過數字下標可以提取出不少字符，但是顯然也有不少字符還是得不到。比如m，S等。這時候該constructor出場了。
怎麼出場呢？很不巧的是上面的字符串中剛好足夠湊出constructor這個字符串，於是我們可以得到：
([])["constructor"]+[]="function Array() { [native code] }"
(![])["constructor"]+[]="function Boolean() { [native code] }"
(+[])["constructor"]+[]="function Number() { [native code] }"
([]+[])["constructor"]+[]="function String() { [native code] }"
({})["constructor"]+[]="function Object() { [native code] }"
([])["constructor"]["constructor"]+[]="function Function() { [native code] }"
但是字符還是不全啊。。。，這個時候，就有人想歪主意了。不過所有的原則就是轉換，例如把數字轉為字符，把一個字符轉為另一個字符。
第一個辦法是window.atob();和window.btoa();這是base64的加密和解密
這個方法是我一開始在網上找到的，後來發現node環境下沒有這兩個方法，所以只能用下面的方法了，不過字符長度增加很多。
第二個辦法是window.escape();和window.unescape();這是html實體的編解碼
比如escape("<")的結果是%3C，取第一個字符得到%；有了%，在加上數字就可以解碼出很多字符了，比如：
unescape("%21")="!"
unescape("%48")="H"
unescape("%57")="W"
第三個辦法是利用數字進制之間的轉換。Number.toString(36);
比如211..toString(31)的結果是6p，再取第二個字符就可以得到p字符了。
下面的代碼可以輸出"Hello World!"，我已經加上注釋了，其中用到的技巧都已經在上面列出來了。
