Yes, they are. React deals with more of the templating side of things (many people use it as the V in MVC, or in some cases as the V & C). But along with React, Facebook also released their Flux architecture which isn't a framework but a new approach to the MV* pattern which many people are using with React. Part of the Flux architecture is a concept called "Dispatcher" which handles the flow of data throughout the app. Facebook did release their code for their implementation of a Dispatcher but not much else. So React + Flux can act as a complete framework, but React alone does not.
