Application State with Redux

Dan Abramov Redux Tutorials¹

• The first principle of Redux is regardless if the app is simple or complex, everything that changes in the application, including the data and UI is contained in a single object that’s known as the state, or state tree.
• A store binds the three principles of Redux: holds current application state object, dispatch actions, and the specification of how the action is dispatched
• getState(): get the states of the current store
• dispatch(): dispatch action linked to the action

• subsribve(): render the content/state, so the UI can be updated

• combineReducers() is helpful because it allows the developer to define the state and action in a single function. It combines the state and the reducer in a single object. This allows the developer to combine all the reducers in a single statement so multiple reducers can be called using a single reducer
