Introduction 🚀 Software design principles are fundamental guidelines that help developers create robust, maintainable, and scalable software systems. Applying these principles leads to code that is easier to understand, test, and evolve over time. This article explores several key design principles and illustrates them with a practical example using Go. Key Design Principles 💡 Here's a breakdown of some essential design principles: SOLID: A cornerstone of object-oriented design, SOLID represents five principles: S ingle Responsibility Principle: A class should have only one reason to change. O pen/Closed Principle: Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification. L iskov Substitution Principle: Subtypes should be substitutable for their base types without altering the correctness of the program. I nterface Segregation Principle: Clients should not be forced to depend on methods they do not use.…
