Delft blue tile reading "You Can't Fix a Bad UX With Great Code" — Developers Tiles of Wisdom

Frontend Architecture

29. You Can't Fix a Bad UX With Great Code

Many 'technical' problems are really UX problems in disguise. Great code can't save bad UX—it can only reduce the pain. Solve the right problem instead.

Software Development

28. Review Your Code

Software Development

19. Always Affirmative

Negations burn brain cycles — every "not" forces the reader to flip the logic. Prefer affirmative names and conditions to make code faster to read and safer to change.

Software Development

17. Refactor Early, Refactor Often

Refactoring isn't a luxury — it's maintenance. Small, frequent improvements prevent technical debt, and tests give you the freedom to improve without fear.

Software Development

16. Write Tests For The Code You Want, Not The Code You Have

AI writes tests around how your code works today — baking in existing bugs. Test for the behavior you want instead, and let TDD safeguard your code's future.

Software Development

12. Don't Use Comments

Comments are often unnecessary or misleading, and wrong comments are worse than none. Write self-explanatory code — and reserve comments for the rare cases that truly need them.
