Redux: Structured State Management for Large Applications
Redux offers a predictable state container for JavaScript apps, making it easier to manage complex state interactions in large-scale applications. This article explores Redux architecture, middleware integration, and strategies for efficient state management to help you build reliable and scalable systems.
Summary
This detailed guide covers Redux from the ground up. Learn how to set up a Redux store, integrate middleware for asynchronous operations, and create scalable state management systems for large applications. Advanced patterns and debugging strategies are also discussed.

Code Examples
1. Simple Redux Counter Example
import { createStore } from 'redux';
const counter = (state = 0, action) => {
switch (action.type) {
case 'INCREMENT': return state + 1;
case 'DECREMENT': return state - 1;
default: return state;
}
};
const store = createStore(counter);
store.dispatch({ type: 'INCREMENT' });
console.log(store.getState());
