Core concepts overview

At the core of the Flux pattern is a unidirectional data flow. It uses some core concepts to achieve this flow. The main idea is when an event is created on a UI, through the interaction of a user, an action is created. This action consists of an intent and a payload. The intent is what your are trying to achieve. Think of the intent as a verb. Add an item, remove an item, and so on. The payload is the data change that needs to happen to achieve our intent. If we are trying to add an item, then the payload is the newly created item. The action  is then propagated in the flow with the help of a dispatcher. The action and its data eventually end up in a store.

• Action and action creators, where we set up an intention and a payload of data
• The dispatcher, our spider in the web that is able to send messages left and right
• The store, our central place for state and state management

All these together form the Flux pattern and promote...
