Introduction to React Hooks

React Hooks were introduced in React 16.8 and completely changed how we write components. They allow you to use state and other React features without writing a class component.

Why Hooks?

Classes were confusing for both humans and machines. They made code reuse difficult and often led to 'wrapper hell'. Hooks allow you to extract stateful logic from a component so it can be tested independently and reused.

Common Hooks

• useState: Allows you to add state to function components.

• useEffect: Handles side effects like data fetching or subscriptions.

• useContext: Lets you subscribe to React context without nesting.

Conclusion

If you are still writing class components in 2025, it is time to upgrade. Hooks are cleaner, more concise, and the future of the library.
