Learning Path Recommendations:

Beginner Level (2-3 months):

• Prerequisites + React Fundamentals + Basic Hooks + Styling
• Focus on: Components, Props, State, useState, useEffect, CSS/CSS Modules

Intermediate Level (3-4 months):

• Advanced Hooks + State Management + Routing + Forms + HTTP Requests
• Focus on: Custom hooks, Context API, React Router, form handling

Advanced Level (4-6 months):

• Performance Optimization + Testing + TypeScript + Build Tools + Frameworks
• Focus on: Next.js, optimization techniques, comprehensive testing

Expert Level (Ongoing):

• Advanced React features + Security + Accessibility + Best Practices
• Focus on: Concurrent features, architecture patterns, team leadership

Remember: Build projects at each level to solidify your understanding. Start with simple components, then progress to full applications!
