Windows development has been increasingly moving to ReactiveX and ReactiveX-style observables as the &quot;best practice&quot; way of handling time and change. (I certainly encourage new Windows projects to take a good, long look at ReactiveUI.)<p>I certainly think that we&#x27;re going to see more migrations to RxJS (or Bacon or other relatives) from Flux (or in addition to Flux).<p>Personally, I&#x27;ve been preferring Cycle (<a href="http:&#x2F;&#x2F;cycle.js.org" rel="nofollow">http:&#x2F;&#x2F;cycle.js.org</a>), which is directly RxJS-based, over React and Flux, but there are an increasing number of options and maybe no &quot;perfect&quot; answers just yet.
