As described initially, the store is the main object that holds the application state tree. It's important to note that there will be a single store in a Redux application. When there is a requirement of splitting the data handling logic, you'll use the Reducer Composition pattern instead of creating many stores.

The following methods are available for Store:

• getState(): Gives the current state tree of the application
• dispatch(action): Used to dispatch an action
• subscribe(listener): Subscribe to the store changes
• replaceReducer(nextReducer): It is an advanced API that replaces the currently used Reducer by Store
