Radio Decoupled communication between your application components with a powerful messaging system Objects Write classes with the same API as your views. They almost sound like components, but there is still a distinction. Define your own HTML element and then just plop it into your application views where you need it. It means that all we need to do in our application is set either the message or the status and the view will render itself. Then, all you need to do is configure each instance of the datagrid with its data.
