Selain pola-pola spesifik, prinsip desain seperti DRY, KISS, YAGNI, dan lainnya memandu penulisan kode yang baik. Prinsip-prinsip yang mudah diingat ini menangkap kebijaksanaan fundamental tentang kesederhanaan, menghindari duplikasi, dan tidak membangun secara berlebihan.
Prinsip inti
DRY (Don't Repeat Yourself) → avoid DUPLICATION → each piece of knowledge has ONE
authoritative representation (duplication → bugs/changes in many places)
KISS (Keep It Simple, Stupid) → favor SIMPLICITY → simple solutions are easier to
understand, maintain, and debug (avoid unnecessary complexity)
YAGNI (You Aren't Gonna Need It) → don't build features/flexibility you don't NEED yet →
avoid speculative generality (build what's needed, not what might be needed)
