AI excels at refactoring: extract functions, convert callbacks → async/await, modernize patterns.

(Plot Twist: That 500-line function you've been scared to touch? AI refactored it in 30 seconds. Time to face your legacy code demons. 👻)

Common Refactorings

• Extract Function: "Extract this logic into a separate function"
• Modernize Syntax: "Convert to async/await"
• DRY: "Remove duplication"
• Type Safety: "Add TypeScript types"

Best Practices

• ✓ Refactor one thing at a time
• ✓ Test before and after
• ✓ AI is great for mechanical refactors, less for architecture changes
