How does redux.createStore work?

redux.createStore is a function in the Redux library that creates a Redux store to manage the application state. When you call createStore, you pass in a reducer function that defines how state is updated based on actions, and an optional initial state. The createStore function returns a store object that provides methods to dispatch actions and subscribe to changes in the state. When an action is dispatched, the store applies the reducer to the current state and the action, producing a new state, which is then broadcasted to all subscribers.
