Best Practices When Using AI Coding Tools
1. Verify Generated Code
Always review and understand the code AI generates:
// ⚠️ VERIFY: Always check for security issues
const result = aiGeneratedCode(); // Don't blindly trust this
2. Use for Repetitive Tasks
AI excels at handling boilerplate:
// ✅ GOOD: Use AI for common patterns
function generateCRUDOperations(model) {
// Let AI generate these patterns
}
3. Combine with Version Control
Always track AI-generated code:
git add .
git commit -m "feat: AI-assisted implementation with manual review"
4. Learning Opportunity
Use AI as a teaching tool:
- Ask for explanations
- Request optimization suggestions
- Get code walkthroughs
