State Management with Hooks and Context
Master useState, useReducer, and Context — and learn exactly which one fits which problem. Build a small shopping cart with local component state, more complex cart logic via a reducer, and cart access from anywhere in the tree via Context.
useState, useReducer, and Context cover the large majority of real state needs — a global store like Redux or Zustand earns its complexity only once state genuinely needs to be shared across many unrelated parts of the tree with complex update logic. This project builds a small shopping cart: local component state with useState, more complex cart logic with useReducer, and cart access from anywhere in the tree via Context.
