Creating a Redux Store

A store holds the whole state of your application, and the only way to change the state inside is by dispatching an action. A store is not a class; it is just an object with a few methods on it.

The store methods are as follows:

• getState(): Returns the current state of your application
• dispatch(action): Dispatches an action and is the only way to trigger a state change
• subscribe(listener): Adds a change listener that is called any time an action is dispatched
• replaceReducer(nextReducer): Replaces the reducer that is currently used by the store to calculate the state
