Redux

What is Redux?

Redux is a predictable state container designed to help in writing JavaScript apps that behave consistently across client, server, and native environments, and are easy to test.

What is the purpose of using redux?

We work with multiple states in JS applications. In a large-scale project, it is difficult to manage states with all layers. If all the states can be stored in a global scope, it would be easy to use from anywhere in the application. Redux can easily solve this problem. Redux stores all the states in a global scope and we can easily use them without any props drilling.

Why use Redux?

When using Redux with React, states will no longer need to be lifted up. This makes it easier for you to trace which action causes any change.

Why is Redux good with React?

Redux can be used with any of the JavaScript libraries like, React, Vue, Angular, etc. But we know that React was designed with the concepts of lifecycle and states. In React, states can only be changed by the setState function. Redux follows the same strategy to manage the states. So, now it is a common trend to use Redux with React.

What is state management in Redux?

State management is essentially a way to facilitate communication and sharing of data across components. It creates a tangible data structure to represent the state of your app that you can read from and write to. That way, you can see otherwise invisible states while you’re working with them.

How Redux works?

The way Redux works is simple. There is a central store that holds the entire state of the application. Each component can access the stored state without having to send down props from one component to another.
