IOC/DI as an alternative to module swapping

IOC-DI.js

// admittedly, dependency injection is better for non-integral dependencies.
// integral dependencies like coding constructs such as array iterators (forEach), 
// type detectors (isArray, isFunction), etc are easier to work with as declared
// dependencies/modules. there are other ways to inject dependencies (e.g.
// constructor params). this is just how we're doing it.
// this example shows the injection of non-integral dependencies
define(function () {

    return {

        // templateEngine must be injected by controller or ioc container
        templateEngine: null,

        // template must be injected by controller or ioc container
        template: null,

        // do something with injected dependencies
        render: function (domNode) {
            var view;
            view = this.templateEngine(this.template);
            domNode.appendChild(view);
        }

    };
