There was a link earlier on HN about declarative programming.

In my opinion that's the best solution to the front-end dev issue.No amount of Backbone based framework ,as good as they are(and I use some) really solve the "how do I build a complex interactive view" problem on the client.

Setting intents and expectations and letting the framework drive the view life cycle solves many issues.AngularJS and React success are a proof of that fact.

So hardest thing to manage in an client app is the view . Backbone never solved that problem.It just had an opinion about the Domain Layer(Backbone models/collections) and the Data Access Layer(ajax).

Didnt try Ampersand but i'm curious as to how it solves that issue.
