• Redux is an open-source JS library used to manage application state.
• React makes use of Redux for constructing the user interface.
• Dan Abramov and Andrew Clark introduced this in 2015.
• The official React binding for Redux is React Redux.
• It creates a process and procedures to interact with the store so that components will not just update or read the store randomly. Similar to the bank.
• They dispatch Actions to the Store to update data,then allows React components to read data from a Redux Store.
• Redux helps apps to scale by providing a sensible way to manage state through a unidirectional data flow model.
• It has no dependencies and is very small.

Uses of Redux :

Store :

• The entire state of your application lists where placed in a store.
• In Redux. It is like a brain responsible for all moving parts.
• It has a dispatch function and then manages the status of the application

Action :

• Action is sent or dispatched from the view which are payloads that can be read by Reducers.
• It is a natural object created to store the facts of the user’s event.
• It consists of information along with type of action, time of occurrence, location of occurrence, its coordinates, and which state it aims to change.

Reducer :

• It updates the store via the state accordingly and read the payloads from the actions.
• At initial state, it is a pure function to return a new state.
