The document discusses the differences between object-oriented programming (OOP) patterns and Gang of Four (GoF) design patterns. It provides examples of GoF patterns like Observer, Strategy, and Decorator and explains that GoF patterns are commonly used design patterns for object-oriented software design. The document encourages learning about GoF patterns to improve one's object-oriented programming skills.
