Predictable state container

• Redux is a predictable state container for JavaScript apps
• Helps you write apps that behaves consistently, run in different environments, and are easy to test.
• Offers live code editing combined with a time traveling debugger.
• Can be use with React, angular , or any other view library.
• Redux is tiny(roughly 2kb), but has a large ecosystem of addons available.

Central store

• With Redux, application state is kept in a store, from which any component can access any state it needs
• State is kept in a single place, improving predictability and traceability
• In React, for example, state has to live in the parent component to share data among siblings
• And so, sharing state between components that are far away from each other is hard state will have to be lifted until a common ancestor is found
• Redux solves this issue by providing a central store holding the entire application state

Features of Redux

• Predictable - Redux helps you write apps that behave consistently
• Centralized application state and logic enables powerful capabilities, such as undo/redo, state persistence, etc.
• Debuggable - Redux DevTools make it easy to trace state, changes
• Time-travel debugging is also possible
• Flexible - Redux works with any UI layer
