JS Namespace function

js-namespace.js

// Core namespace
var app = app || {};

app.namespace = function(namespace) {
	var spaces = namespace.split('.');

	var nspace = function(spaces, index, progress) {
		// Check the namespace exists
		if (typeof spaces[index] === "undefined") { return; }

		// Create the current namespace
		if (typeof progress === "undefined") {
			// We are starting at the root level (will always be app)
			progress = app;
		} else {
			// We are continuing on a namespace
			var newSpace = spaces[index];
			progress[newSpace] = progress[newSpace] || {};
			progress = progress[newSpace];
		}

		// Go deeper down the chain
		nspace(spaces, index + 1, progress);
	};

	// Start namespace creation
	nspace(spaces, 0);
};



//
// Usage
//
// Create namespaces off 'app' of unknown lengths e.g.
//

app.namespace("app.views.homepage");
app.views.homepage = {};

app.namespace("app.views.loginmenu.loggedOut.view");
app.views.loginmenu.loggedOut.view = {};
