React_Function_Component

🧱 Overview

React component patterns are reusable structures that help developers create scalable, maintainable, and efficient user interfaces. These patterns address common challenges like state management, props passing, and component composition.

✅ Key Patterns

  1. Function Components

    • Preferred for simple UI logic.
    • Use useState and useEffect hooks for state and side effects.
    • Example: A basic button component.

  2. Class Components

    • Legacy approach for complex state logic.
    • Utilize constructor, render, and lifecycle methods.
    • Example: A form component with validation.

  3. Higher-Order Components (HOC)

    • Reusable component logic via wrapper functions.
    • Enhances code reuse and modularity.
    • Example: Auth wrapper for protected routes.

  4. Render Props

    • Share component logic through a function prop.
    • Flexible for dynamic UI rendering.
    • Example: Custom data fetching logic.

  5. Uncontrolled vs. Controlled Components

    • Controlled components manage state via props.
    • Uncontrolled components use DOM APIs directly.
    • Example: Form input with and without state control.

🚀 Best Practices

  • Use Custom Hooks for Reusable Logic
    • Avoid duplicating code across components.
  • Leverage Component Composition
    • Break down complex UIs into smaller, focused components.
  • Optimize with Memoization
    • Use React.memo to prevent unnecessary re-renders.
  • Follow the Single Responsibility Principle
    • Each component should handle one specific task.
