Clean Code by Robert C. Martin - Chapter Summaries

Chapter 1: Clean Code

• Clean code is simple and elegant - reads like well-written prose
• Clean code is focused - each function, class, and module has a single responsibility
• Clean code is written by someone who cares - attention to detail is evident
• Clean code can be read and enhanced by others - not just the original author
• Clean code has meaningful names - variables, functions, and classes have intention-revealing names
• Clean code has no duplication - follows the DRY principle
• Clean code runs all tests - is thoroughly tested and works correctly
