Part 2: Advanced Topics
Now that you’ve mastered the basics, let’s explore some more advanced concepts that will take your skills to the next level.

Building on the Fundamentals
In Part 1, we covered the foundation. Now we’ll build on that knowledge with more complex patterns and techniques.
Advanced Pattern 1: Component Architecture
Understanding component architecture is crucial for scalable applications:
interface ComponentProps { title: string; children: React.ReactNode; variant?: "primary" | "secondary";}
const AdvancedComponent: React.FC<ComponentProps> = ({ title, children, variant = "primary",}) => { return ( <div className={`component component--${variant}`}> <h2>{title}</h2> {children} </div> );};Advanced Pattern 2: State Management
Managing state effectively is key to building robust applications.

Deep Dive: Best Practices
Here are some best practices gathered from production experience:
- Keep it Simple - Complexity is the enemy of reliability
- Document Everything - Future you will thank present you
- Test Early, Test Often - Catch bugs before they catch you
Code Quality Checklist
Pro Tip: Use this checklist before every commit
- Code is properly formatted
- Tests are passing
- Documentation is updated
- No console.log statements
- Error handling is in place
Performance Considerations
| Metric | Target | Actual |
|---|---|---|
| Load Time | < 2s | 1.5s |
| TTI | < 3s | 2.8s |
| CLS | < 0.1 | 0.05 |
