Redux

Redux is a powerful state management library for JavaScript applications; commonly used with libraries/frameworks like React. It provides a predictable state container for managing the application's state and helps to make state mutations predictable by imposing certain restrictions on how and when updates can occur. Redux operates on a unidirectional data flow principle; where the state of the application is stored in a single immutable state tree; and changes are made by dispatching actions; which are plain JavaScript objects describing the change. These actions are then handled by pure functions called reducers; which specify how the state should change in response to the actions.
