Execute module pattern function before declaration

Question

I'm using some kind of module pattern as described here :

var Module = function(){
  function foo(){}
  return{
    foo:foo,
  }
}();

it can be called with

Module.foo();

However, it only works when the call is made after the declaration.

For readability purpose, is there any way to call it before the declaration ?

Why have a special method foo for that, if you want to execute it right away? Just execute the code during the module instantiation. — Bergi

foo is not meant to be called right away. I just want the module code to be at the bottom of my single page script. — kursus

Why would it then be above the declaration if it is not intended to be executed before it? Maybe you could show your "whole" single-page script (all relevants part of it in expected order). — Bergi

You could wait for the document ready event. If you're using jquery it could be something like

$(document).ready(function () {
    Module.foo();
});


var Module = (function () {
    //Definition for Module
})();

The document ready function will wait for the document to be loaded to call your function. So it will parse all the javascript before it executes.
