Part of our decision to prioritize integration with other technologies/frameworks is so that more mature tools like Angular or React can do the heavy lifting on application logic while Famous focuses on animation and layout. We learned a lot about this balance from our time building Famo.us/Angular.
In other words, we're not trying to be 'everything for everyone' out of the gate, but we'd love to be 'something for everyone,' and the 'something' we're focusing on is what what Famous is good at: user interfaces, interactions, and animations.
