What is redux toolkit in react

React Redux Toolkit (RTK) is a popular library for building applications with the React library and the Redux state management library. It provides a set of tools and utilities that simplify the process of working with React and Redux, making it easier to build scalable and maintainable applications. 

One of the key features of RTK is its createSlice function, which makes it easier to create and manage redux reducers and actions. With createSlice, you can define your reducer logic and action creators in a single place, and RTK will handle the creation of the corresponding reducer and action types for you. This helps to reduce boilerplate code and make your redux logic easier to understand. 

Another useful feature of RTK is its configureStore function, which helps you to configure and create a Redux store for your application. It provides a set of options that allow you to customize the store to your needs, such as enabling the Redux DevTools extension or adding middleware for async actions. 

In addition to these core features, RTK also provides a number of utility functions and hooks that can be used to simplify common Redux tasks, such as dispatching actions, selecting data from the store, and managing side effects. 

Overall, RTK is a powerful tool that can help you to build efficient and scalable React-Redux applications more easily. It provides a set of powerful features that make it easier to work with React and Redux, and helps you to avoid common pitfalls and reduce boilerplate code. If you are building a React-Redux application, it is worth considering using RTK to help you get up and running more quickly.
