While both Context API and Redux are used for state management in React applications, Context API is better suited for simpler applications with basic state needs, while Redux is more powerful and designed for complex applications with intricate state management requirements, offering features like centralized state, predictable data flow, and advanced debugging tools.

The following image is the visual of Redux vs Context Api .

Key Differences:

Complexity:
Context API is simpler to set up and use with less boilerplate code, making it ideal for small projects, while Redux requires more setup and understanding due to its robust state management system.

State Management:
Context API allows sharing state across components within a component tree without prop drilling, but lacks the centralized state management and predictable updates of Redux.

Scalability:
Redux scales well for large applications with complex state interactions due to its structured approach with actions, reducers, and a single store, whereas Context API can become difficult to manage in large applications with many nested components.

Learning Curve:
Context API has a shallower learning curve as it's a built-in React feature, while Redux requires understanding concepts like actions, reducers, and middleware. 

When to use Context API:
* Small applications with simple state needs
* Passing global data like theme settings or user authentication across components without excessive prop drilling

When to use Redux:
* Large and complex applications with intricate state interactions
* Scenarios where you need a centralized store for predictable state updates and debugging capabilities
* Applications with multiple developers where maintaining consistent state management is crucial

How the data folows through Redux...

Building Parts of redux:

1. Action
2. Reducer
3. Store

How the data folows through Redux ? Actions: Actions are a plain JavaScript object that contains information. Actions are the only source of information for the store. Actions have a type field that tells what kind of action to perform and all other fields contain information or data. And there is one other term called Action Creators, these are the function that creates actions. So actions are the information (Objects) and action creator are functions that return these actions.

Reducers: As we already know, actions only tell what to do, but they don't tell how to do, so reducers are the pure functions that take the current state and action and return the new state and tell the store how to do.

Store: The store is the object which holds the state of the application.
Functions associated with Store:
* createStore() - To create a store
* dispatch(action) - To change the state
* getState() - for getting current state of store.

Redux benefits

Redux, you'll see several benefits that are commonly discussed: Predictable state updates make it easier to understand how the data flow works in the application. The use of "pure" reducer functions makes logic easier to test, and enables useful features like "time-travel debugging".
