Your application state is global, and your component state is local. Flux or a flux-like library like Redux, use what they call "stores" to hold application state. That means any component, anywhere in the app can access it (kind of like a database) so long as they hook into it.

Component state however, lives within that specific component. As such, it can only be updated within that component and passed down to its children via props.
