Hooks are a powerful addition to React (introduced in version 16.8) that let you use state and other React features without writing a class component. They allow you to reuse stateful logic and manage component lifecycle in a more declarative and composable way.

Why Hooks?

• Reusing Stateful Logic: Hooks let you extract stateful logic from a component so it can be tested independently and reused.
• Simpler Components: Function components with Hooks are often easier to read, write, and understand than class components with their `this` keyword, binding, and lifecycle methods.
• No More Classes: If you prefer functional programming paradigms, Hooks allow you to build your entire application with function components.

Commonly Used Hooks:

• `useState`: Lets you add state to function components.
• `useEffect`: Lets you perform side effects in function components (similar to `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount` in classes).
• `useContext`: Lets you subscribe to React context without introducing nesting.
• `useReducer`: An alternative to `useState` for more complex state logic.
• `useCallback` and `useMemo`: For performance optimizations.

Rules of Hooks:

1. Only call Hooks at the top level of your React function or custom Hook.
2. Only call Hooks from React function components or custom Hooks.
