creating javascript modules

Question

I would like to know how can I create a module and manually create more instances of that module without impacting the global scope.

Right now I have something similar to this piece of code:

var myModule = (function(){
    ...
})();

myModule is at this point in the global scope of my app.

What can I do to encapsulate this somewhere and call a new instance of it anytime I need one?

I am looking for something similar with Require.js or Angular.

Have you looked at commonJS? Are you looking to do this client-side, server-side, or both? — johnnyutah

It isn't only for third party libraries. var coolModule = ["wow", "neat", "module"]; module.exports = coolModule; Then in another file: var coolModule = require("coolModule"); Is that what you have in mind? — johnnyutah

Yes. But the result of require I want to be a new instance of coolModule — tzortzik

Got it. Why not make coolModule a javascript "class" and then call that constructor on module.exports? something like this — johnnyutah

var myScope={};

(function(window) {

function Module(){
    console.log('new instance of Module');
};

Module.prototype.someFunction = function(){

};

window.myScope.Module = Module;

}(window));

myModule = new myScope.Module();

Something like this?

The code is not working. Chrome says TypeError: Cannot set property 'Module' of undefined
