Question

I\'m reading the Javascript Guide from Mozilla And when they contrasted JS to Java , It got me thinking, Java code is easily split up with each class in his own file. after futh

You should have one global namespacing object which every module has to access and write to. Modify your files like so:

// employe.js

window.myNameSpace = window.myNameSpace || { };

myNameSpace.Employee = function() {
    this.name = "";
    this.dept = "general";
};

and Manager.js could look like

// Manager.js

window.myNameSpace = window.myNameSpace || { };

myNameSpace.Manager = function() {
    this.reports = [];
}
myNameSpace.Manager.prototype = new myNameSpace.Employee;

This is of course a very simplified example. Because the order of loading files and dependencies is not child-play. There are some good librarys and patterns available, I recommend you looking at requireJS and AMD or CommonJS module patterns. http://requirejs.org/
