Clean code principles: 1) Meaningful names (getUserById not getData). 2) Small functions (do one thing well, under 20 lines). 3) No magic numbers (MAX_RETRIES = 3 not just 3). 4) DRY but not obsessively (duplicate is better than wrong abstraction). 5) Comments explain why, not what. 6) Consistent formatting. 7) Error handling that does not obscure logic. 8) Tests as documentation. The best code reads like well-written prose — your future self will thank you.
