React — React Redux - Introduction

Redux is a state management library often used with React. It helps manage global state in large applications using actions, reducers, and a store.

import { createStore } from 'redux';

const reducer = (state = { count: 0 }, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    default:
      return state;
  }
};

const store = createStore(reducer);

store.dispatch({ type: 'INCREMENT' });
console.log(store.getState());
