A similar thing can be done in Backbone by having a bare bones instance of the Event class that all other views and objects can listen and trigger events on. Postal probably does a lot more than this, but if you are already using backbone this is a simple way of decreasing coupling with very low overhead.

You can also accomplish the same effect in Angular by creating several "controllers" with focused responsibilities, then communicating via events with $rootScope.$broadcast (publish) and $scope.$on (subscribe). I've been using this pattern a lot recently and have found it does a great job encouraging separation of concerns.

The backbone object itself now extends Events, so you can use

    Backbone.on('got_weather', function...)
    Backbone.trigger('got_weather', {})

I've fallen in love with Knockout (http://knockoutjs.com) -- it's even simpler than this.

Completely abstracts away events and updating the DOM. It even tracks all the dependancies for you.

We've been using Knockout with pretty decent success so far at my company.

It's not a full-blown web framework, but that's part of the reason why we chose it instead of something like Angular.
