As someone who has written several things with Flux and Flux-esque architecture, I see it as a step in the middle, rather than where things are ending. It&#x27;s not a large step from Flux (Stores update themselves in response to actions) to Redux (Model the entire application as reducers on a sequence of Actions) to RxJS Observables.<p>What&#x27;s shared in there is the idea that unidirectional data flow is a whole lot easier to reason about, model, and simulate than 2-way data flow. Everything else is semantics.
