What’s the on roadmap for Backbone.js beyond 1.0?

The essential premise at the heart of Backbone has always been to try and discover the minimal set of data-structuring (Models and Collections) and user interface (Views and URLs) primitives that are useful when building web applications with JavaScript. We’re going to keep hunting for that specific type of feature, and if you think that you’ve found one, please send it on in. In an ecosystem where overarching, decides-everything-for-you frameworks are commonplace, and many libraries require your site to be restructured to suit their look, feel, and default behavior — Backbone should continue to be a tool that gives you the freedom to design the full experience of your web application.

Suffice to say, over the past 2 and a half years, what’s been built with Backbone has surpassed our wildest expectations. I’m looking forward to being surprised by more great apps.

Whenever the “Which Javascript MVC framework should I use?” question comes up, Backbone.js is always near the top of the list. Glad to see that they’ve reached a milestone in development.
