React Redux is the official React UI bindings layer for Redux. It lets your React components read data from a Redux store, and dispatch actions to the store to update state.
Why Use React Redux?
Redux itself is a standalone library that can be used with any UI layer or framework, including React, Angular, Vue, Ember, and vanilla JS. Although Redux and React are commonly used together, they are independent of each other.
If you are using Redux with any kind of UI framework, you will normally use a "UI binding" library to tie Redux together with your UI framework, rather than directly interacting with the store from your UI code.
React Redux is the official Redux UI binding library for React. If you are using Redux and React together, you should also use React Redux to bind these two libraries
Reasons to Use React Redux
It is the Official Redux UI Bindings for React
While Redux can be used with any UI layer, it was originally designed and intended for use with React. There are UI binding layers for many other frameworks, but React Redux is maintained directly by the Redux team.
As the official Redux binding for React, React Redux is kept up-to-date with any API changes from either library, to ensure that your React components behave as expected. Its intended usage adopts the design principles of React - writing declarative components.
It Implements Performance Optimizations For You
React is generally fast, but by default any updates to a component will cause React to re-render all of the components inside that part of the component tree. This does require work, and if the data for a given component hasn't changed, then re-rendering is likely some wasted effort because the requested UI output would be the same.
If performance is a concern, the best way to improve performance is to skip unnecessary re-renders, so that components only re-render when their data has actually changed. React Redux implements many performance optimizations internally, so that your own component only re-renders when it actually needs to.
In addition, by connecting multiple components in your React component tree, you can ensure that each connected component only extracts the specific pieces of data from the store state that are needed by that component. This means that your own component will need to re-render less often, because most of the time those specific pieces of data haven't changed.
