   A short Angular narrative
   › Mr White: I’m trying to set a variable on my scope and it isn’t
   reflecting in the UI.
   › Mr Blue: I ususaly just use “if (!$scope.$$phase)
   $scope.$apply() “.
   › Mr Red: Don’t do that! You should use “$timeout()”, because
   “if (!$scope.$$phase) $scope.$apply() “ is an anti-pattern.
   › Me: THAT IS ALL AWFUL.

   Inspiration
   › Given angular v1 is effectively obsolete*
   › And given my recent pause for thought
   › And given there is a lot of noise around React as a
   front-end framework
   › When selecting a front-end framework for a new web
   project
   › Then [Insert conclusion here]
   * http://www.techinfine.com/post/231575/Announcements-from-ng-confsome interesting news at ng-confjust last week has injected some hope into
   Angular V1, although at the moment it is just that –hope.

    Flux and async
    › Handling asynchronous interactions with the server is
    easy enough with Fluxxor, but isn’t strictly in-built.
    › Need to dispatch actions on start, done and fail of
    interaction, and stores are used to supply state that the
    view can use to inform the user that things are
    happening.
