AM I THE ONLY ONE?

It depends on what one calls a model. If the model is JSON-like data and the view is generated HTML+CSS, then the JS have very nice separation. In fact it is better than many C++/Java frameworks as JS view is not updated until the whole code that is triggered by the current event is run. Effectively in JS one can get very complex updates without any flicker.

Also JS allows nicely preserve GUI state with #bookmarks which gives as a bonus an extra way to navigate the GUI using the address bar. Just try that that in any native application - most of them have hard time recovering just the state where they were before the user closed them.
