Clean Code
Code that is easy to understand, simple to modify, and clearly expresses the intent of the programmer. A philosophy popularized by Robert C. Martin.
Definicao
Clean code follows principles from Robert Martin's book "Clean Code": meaningful names, small focused functions, clear intent, minimal dependencies, and no duplication (DRY). Clean code reads like well-written prose — each function tells a story at its level of abstraction. The Boy Scout Rule says to always leave code cleaner than you found it.
Por que e importante
Developers spend 10x more time reading code than writing it. Clean code reduces this cognitive load, making maintenance faster and less error-prone. Studies show teams with clean code practices have 50% fewer bugs and onboard new developers 3x faster.
Exemplo
Instead of: function calc(a,b,c) { return a*b-c/2; } — clean code would be: function calculateDiscountedTotal(subtotal, discount, tax) { return subtotal * discount - tax / 2; }
