In this article, we will implement ReactJS application state management using Redux Toolkit with a CRUD example. Redux Toolkit For State Management: In the ReactJS application to share data between components consistently, we can use the Redux Toolkit. The Redux Toolkit is built on top of the standard 'Redux' to overcome a few concerns like 'complexity to configure the redux', 'avoiding additional packages to integrate with redux', 'to avoid the too much boilerplate code generated by redux'. The main building component of Redux Toolkit are: Actions - actions represent events to trigger the reducer to update data into the store. Reducers - In general in 'Redux' reducer pure function to create the state instead of changing the state. But in 'Redux Toolkit' we can mutate the state directly, but internally using the 'Immer' library our logic generates a new state instead of mutating the existing state. Store - object where we store o
