For JavaScript apps, Redux is a predictable state container. It enables you to create apps that act consistently across platforms (client, server, and native) and are simple to test.

Redux is made up of three components: actions, stores, and reducers.

Redux is widely used alongside React to manage state and state transformations, while React has its own definition of state. It's important to know when to use which of these libraries. Even if you decide to use Redux in your project, you'll need to decide how much of your data will be saved in Redux.

Redux Thunk is a middleware that allows you to call action creators that instead of returning an action object, return a function. Once the asynchronous operations are complete, that function obtains the store's dispatch method, which is then used to dispatch standard synchronous actions inside the function's body.

Conclusion. Redux is a fantastic solution for creating large-scale apps that need to manage global state. More lightweight technologies, such as MobX, PushState, or React Context, are available for simpler instances. A big benefit of Redux, from the engineers' perspective, is that it improves the developer experience.
