Too much recursion 

Higher Order Javascript

 

Here I'll post some small functions. Hopefully a few will give you a smile :)

myFun=function(){
  var me=arguments.callee;
  me.browser= (document.all) 
   ? function(){alert("Hi I'm IE")} : function(){alert("Hi I'm FireFox")}; 
 myFun=function(myFun){
   arguments.callee.caller.browser();
  alert(myFun);
 }
 myFun(myFun);
}();

This function at first glance exhibits some strange behaviour. Not the fact that it tests for document.all ;), but the result of alert(myFun). I thought it would have been == arguments.callee.caller, like this:

myFun=function(){
  var me=arguments.callee;
  me.browser= (document.all) 
   ? function(){alert("Hi I'm IE")} : function(){alert("Hi I'm FireFox")}; 
 myFun=function(myFun){
   me.browser();
  alert(arguments.callee.caller+"\n~~~~~~~~~~\n"+myFun);
 }
 myFun(me);
}();
alert(myFun);

Result of alert(myFun): undefined... and

myFun=function(){
  var me=arguments.callee;
  me.browser= (document.all) 
   ? function(){alert("Hi I'm IE")} : function(){alert("Hi I'm FireFox")}; 
 myFun=function(){
   me.browser();
  alert(arguments.callee.caller+"\n~~~~~~~~~~\n"+myFun);
 }
 myFun(me);
}();
alert(myFun);

Result of alert(myFun): undefined... and here is an anonymous function:

new function(){
    arguments[0].message();
}({message:function(){alert('called by null')}});
