It is back to fat client, with a server publishing the UI and the content, but the UI runs in the client.  JS supports client-side behaviors to respond to mouse over, hover, move?, click, selection, etc.  It is a professional look and feel and accepted industry wide - broad support in modern browsers.

Err, no. The DOM lets you manipulate HTML:

The DOM is JS's view of the HTML page, and it can manipulate it. That's all there is to it (if you cut through the piles of marketing bs). It's a very simple idea, and as often, those are the powerful ones ;)

E.g. if you want to hide or show a control in JS you change attributes on the DOM which the browser then renders.

This has nothing whatsoever to do with a server. As I pointed out earlier ;)
