This week’s updates dive into three important topics. New chapters:
- Smell: Uncommunicative Name
- Solution: Rename Method
- Solution: Extract Decorator
- Smell: Mixin
- Solution: Replace mixin with composition
The first two chapters discuss the importance of naming methods and classes. We discuss how to use class and method names to improve readability and discover classes and methods that need refactoring.
Another chapter demonstrates how to extract concerns in a repeatable, combinable way using the Decorator pattern.
The last two chapters provide tips for identifying and fixing mixin abuse.
