I say with confidence as a former
UIKit author: React's model for the UI

React Native is a *huge* deal.

UI = VIEW(DATA)
View layer is an function from data to user

One can merge the MVC roles played
by an object, making an object, for
example, fulfill both the controller
and view roles—in which case, it
would be called a view controller.
