Clean Code Notes — Chapter 3: Functions

Chapter 3 of Clean Code by Robert C. Martin emphasizes writing small, focused, and clear functions. Key principles include keeping functions short, ensuring they do one thing, using descriptive names, minimizing function arguments, following command-query separation, preferring exceptions over error codes, and adhering to the Don't Repeat Yourself (DRY) rule. These practices enhance code readability, maintainability, and overall quality.
