Redux is &quot;inspired by&quot; Flux, but it&#x27;s not Flux. One very big (and positive) difference: with Flux each store notifies the React components when it&#x27;s updated, independently from the other stores.<p>This means that, if you update two stores with a single action, this will provoke two renders, the first one with inconsistent data between the two stores (in other words, there is no way to update all the stores atomically from the React components point of view).<p>Redux, instead, updates the whole store, and only then notifies the React components.
