...truth.
In every Flux implementation I've seen Actions are basically event strings turned into objects, like traditionally you'd have an event named "anchor:clicked" but in Flux it would be defined as AnchorActions.Clicked. They're even so "dumb" that most implementations have separate Dispatcher ob...
