## What it is
Redux is a tiny (2kB) JavaScript library for predictable, centralized global state management using a unidirectional data flow with actions and reducers. It works with any UI layer (most commonly React), supports time-travel debugging via DevTools, and is best used through its official companion, Redux Toolkit.

## Use cases
- manage global application state in a React app
- centralize state shared across many components
- implement undo/redo and state persistence
- debug state changes with time-travel tooling
- share state between client, server, and native environments
- write testable state update logic with reducers

## When to choose
- you have complex, frequently-changing global state shared across many parts of an app
- you need predictable, traceable state updates and powerful debugging
- you want a battle-tested, framework-agnostic state container with a large ecosystem
- you want centralized state enabling undo/redo or persistence

## When to avoid
- your app has mostly simple local UI state better handled by useState or useReducer
- you want minimal boilerplate without adopting Redux Toolkit conventions
- you need only server-state caching, where tools like React Query may fit better
- your team is unwilling to learn Redux's actions/reducers/middleware model
