Why Code Hygiene Matters More Than You Think
"It's just a console.log, what's the worst that could happen?"
Actually, quite a lot.
The Hidden Costs of Poor Hygiene
1. Security Risks Console.log statements can leak sensitive information: - User data - API responses - Internal state
Browser developer tools are accessible to anyone. Your debug logs are too.
2. Performance Impact - Unused imports increase bundle size - Console statements add runtime overhead - Dead code confuses treeshaking
3. Maintainability When you see a codebase with TODO comments from 2 years ago, what does it tell you? That issues are ignored, corners are cut, and the codebase isn't maintained.
Common Hygiene Issues
- •. **console.log, console.warn, console.error** — Remove or replace with proper logging
- •. **Unused imports** — Delete them
- •. **TODO/FIXME/HACK comments** — Resolve or remove
- •. **Hardcoded colors** — Use a design system
- •. **TypeScript `any`** — Type it properly
- •. **Empty components** — Delete or implement
