useState or useReducer? A Complete Guide to React State Hooks
In this tutorial you will learn when to prefer React’s useState—ideal for simple, independent state like counters, booleans, or single values—and when to reach for useReducer, which centralizes complex updates in a pure reducer, manages nested objects and multi-field forms, supports context-based dispatch, yields testable, predictable updates, and can optimize performance. You’ll see practical code examples, common pitfalls to avoid, and a decision cheat-sheet to guide your choice.
