## 🆕 Expert Remediation Examples

### Before vs. After: Automatic Code Fixing

**❌ Before (Problematic Code):**
```typescript
const MyComponent = () => {
  const apiKey = "sk-1234567890abcdef"; // Hardcoded secret
  const [data, setData] = useState([]);
  
  useEffect(() => {
    console.log("API Key:", apiKey); // Sensitive logging
    fetch('http://api.example.com/data') // HTTP instead of HTTPS
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => { // Memory leak
      console.log('Polling...');
    }, 1000);
  }, []);

  return (
    
      {data.map(item => ( // Performance issue
        {item.name}
      ))}
    
  );
};
```

**✅ After (Expert Remediation):**
```typescript
interface Props {
  children?: React.ReactNode;
  onPress?: () => void;
}

const MyComponent: React.FC = () => {
  // TODO: Add API_KEY to your environment variables
  const apiKey = process.env.API_KEY || Config.API_KEY;
  const [data, setData] = useState([]);
  
  useEffect(() => {
    // Removed sensitive logging for security
    // console.log('[REDACTED - contains sensitive data]');
    
    // Upgraded to HTTPS for security
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => {
      console.log('Polling...');
    }, 1000);
    
    // Cleanup intervals to prevent memory leaks
    return () => {
      clearInterval(interval);
    };
  }, []);

  return (
     item.id?.toString() || index.toString()}
      renderItem={({ item }) => (
        {item.name}
      )}
    />
  );
};

const styles = StyleSheet.create({
  itemText: {
    color: 'red'
  }
});

export default React.memo(MyComponent);
```

**🎯 What Got Fixed Automatically:**
- ✅ **Security**: Hardcoded API key → Environment variable
- ✅ **Security**: Sensitive logging → Sanitized
- ✅ **Security**: HTTP → HTTPS upgrade
- ✅ **Performance**: ScrollView + map → FlatList with keyExtractor
- ✅ **Memory**: Added interval cleanup to prevent leaks
- ✅ **Best Practices**: Inline styles → StyleSheet.create
- ✅ **Type Safety**: Added TypeScript interface
- ✅ **Performance**: Wrapped with React.memo
