Should you ever have to work on a web application again, just don’t think about it twice; Ext is an amazing piece of free software, light-years away from anything you’ve seen before.
Ext is a JavaScript framework, unlike any other in the market. It consists of a great mix of high level API documentation, coherent coding style, and excellent support, going beyond the mere lines of code. It is the first time in 10 years of web development that I really find a web platform worth that name.
Ext is more than a framework: is the DOM as it should have been in the first place.
