Flux vs Redux: What are the differences?

# Introduction

Key differences between Flux and Redux

1. **State Management**:
   Flux uses multiple stores to manage the application state, while Redux utilizes a single store with a normalized state structure.

2. **Data Flow**:
   In Flux, data flows in a unidirectional path, passing through actions and stores, whereas Redux follows a strict unidirectional data flow pattern which simplifies debugging and understanding the application.

3. **Immutability**:
   Redux emphasizes immutability, making all state updates and changes immutable. Flux, on the other hand, does not enforce immutability by default.

4. **Middleware**:
   Redux provides a built-in middleware feature that allows developers to customize behavior between dispatching an action and the moment it reaches the reducer. Flux, on the other hand, lacks a built-in middleware mechanism.

5. **DevTools**:
   Redux comes with powerful tools like Redux DevTools that enable developers to track actions, state changes, and performance optimizations easily. Flux does not have standard tools like Redux DevTools for such purposes.

6. **Community Ecosystem**:
   Redux has a larger and more active community compared to Flux, which results in a wider range of libraries, tools, and resources available for Redux developers.

In Summary, Flux and Redux differ in their state management approach, data flow structure, emphasis on immutability, middleware support, devtools availability, and community ecosystem size.

    What is Flux?

    Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow. It's more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code.

    What is Redux?

    It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test. t provides a great experience, such as live code editing combined with a time traveling debugger.
