💡 Best Practices Menggunakan AI Tools

1. Prompt Engineering untuk Developer

# Template Prompt yang Efektif:

## For Code Generation:
"Create a [language] [type of code] that [specific functionality]
Requirements:
- [requirement 1]
- [requirement 2]
Include error handling and comments."

## For Debugging:
"I have a bug in my [language] code. Here's what's happening:
Expected: [expected behavior]
Actual: [actual behavior]
Code: [paste code]
Help me identify and fix the issue."

## For Code Review:
"Review this [language] code for:
- Performance issues
- Security vulnerabilities  
- Best practices
- Potential bugs
Code: [paste code]"

2. AI-Assisted Development Workflow

graph TD
    A[Planning] --> B[AI Architecture Design]
    B --> C[Code Generation]
    C --> D[AI Code Review]
    D --> E[Testing with AI]
    E --> F[AI Documentation]
    F --> G[Deployment]
    G --> H[AI Monitoring]

3. Security Considerations

// ❌ Jangan share sensitive data dengan AI
const apiKey = "sk-1234567890abcdef"; // Jangan paste ke AI

// ✅ Gunakan placeholder
const apiKey = process.env.API_KEY; // Safe untuk AI review

// ❌ Jangan share production URLs
const endpoint = "https://api.mycompany.com/users";

// ✅ Gunakan generic examples
const endpoint = "https://api.example.com/users";

4. Quality Control

# Checklist untuk AI-generated code:
"""
✅ Code Review Checklist:
□ Functionality works as expected
□ Error handling implemented
□ Security best practices followed
□ Performance optimized
□ Code style consistent
□ Tests included
□ Documentation added
□ No hardcoded values
□ Proper variable naming
