[...]Explains what namespaces are in JavaScript, how, when and why to use them.

Also explains how to use Ext.namespace, a convenience method in the Ext JS library to setup namespaces.[...]

I completely agree with your points about the value of namespacing. In fact, I explored this topic in more depth on my blog, recently: http://higher-order.blogspot.com/2008/02/designing-clientserver-web-applications.html

That posting explores the benefits of namespacing, but goes further showing also how one can use an ‘import’ like feature to bring a long namespace into scope. For example you could write stuff like:

namespace(”com.trifork.tribook.model”);
using(com.trifork.tribook.model).run(function(m){
var rsvReader = new Ext.data.JsonReader({
root: “reservations”
}, m.Reservation);//converts JSON objects to Reservation objects

m.Room = Ext.data.Record.create([...]);//detail omitted
});

This can really help you structure large JS/Ext applications.
