Don&#x27;t know, I never liked two-way bindings :) &lt;MuseumTech&gt;Adobe Flex added those at some point but it was a complete downgrade from the simpler one way bindings + events.&lt;&#x2F;MuseumTech&gt;<p>A central state atom has pros (debug tooling and the fabled undo for free being the main ones?) and cons. The cons affects me more than the pros. Clojure&#x27;s Om and React+redux maintain a central atom but still allow for local state in a pinch.<p>I appreciate your comment but I wish it was a bit more constructive; Why do you think a central state atom is so much better ? How can one write ready-to-use smart components with central state ? (e.g ReactTransitionGroup)
