 js does not perform type checking, and the array can store anything. So I thought that the array can be stored in the function, the following is a detailed introduction to the next

One of the biggest differences between JS and Java is that functions are also considered data and can operate like an object in Java. And because JS does not perform type checking, the array can store anything. So I wondered if the array could hold a function.     Implement the following functions:    functions are stored in the array after the call (can not be stored according to the parameters)     Then you can use a large function to manipulate the array and call the functions.     Originally I wanted to use this method to perform a undo function (that is, each function stores itself in, and if undo eliminates the last function and executes the entire queue), it feels too cumbersome. However, function Array function is implemented: Paste the jsp    code as follows: <%@ page language= "java" contenttype= "text/html;" Charset=iso-8859-1 "  pageencoding=" iso-8859-1 "%>  <! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://" >  <html >  <head>  <meta http-equiv= "Content-type" content= "text/html; Charset=iso-8859-1 ">  <title>MothedList</title>  </head>  <body>  <input type= "button" onclick= "FF ()"/>  <script type= "text/javascript" >  list = new array;  F1 = function F1 (flage) {  alert ("F1");  if (flage)   List.push (F1); }  F2 = function F1 (flage) {   ALert ("F2");  if (flage)   List.push (F2); }  function ff () {  F1 (True);  F2 (true);  F = List.pop ();  f (false);  F = list.pop ();  f (); }  </script>  </body>  & lt;/html>
