What are React Hooks, and why are they useful?

Sunita • Jul 18, 2026 • 4 views

I know React Hooks were introduced to simplify component development, but I'm not sure why they are preferred over class components. Could someone explain the most commonly used Hooks with examples?

React Hooks are functions that allow functional components to use state, lifecycle methods, and other React features. Common Hooks include useState, useEffect, useContext, useMemo, and useRef. Hooks make code easier to read, simplify logic reuse, and eliminate the need for class components in most scenarios.
