what is Flux?

What is Flux?
 - action, dispatch(controller), store(data layer), view(view can pass an action back to the dispatcher)
    - action creators are like the methods and helpers for the dispatcher
    - dispatcher makes sure there are no cascading effects or i.e. one action in the store at a time
    - store is where the logic is done and manipulates state then passes down to child in the view
 - show a image of a flux diagram
 - Its a pattern not a framework
   - maybe examples of common implementations of the pattern (redux)
Why Flux?
 - compare and contrast the MVC model
  - trying to avoid cascading effects by preventing nested updates(what does this mean?)
     - allow data layer to finish processing before triggering any additional actions
     - this flows data only in one direction ( action -> store -> view -> action -> store -> view...)
 - keep state close to the logic that updates that state
when to implement flux? 
 - useful on small and/or large projects?
