The original title is "Single Responsibility Principle explained with TypeScript code examples"

Short summary

The Single Responsibility Principle (SRP) states that a class should have only one reason to change, avoiding the anti-pattern of a God Class that handles validation, persistence, notifications, and logging all at once. The article uses a Swiss Army Knife vs. scalpel analogy and provides TypeScript code examples showing how to refactor a monolithic UserService into separate Validator, Repository, EmailService, ReportGenerator, and Logger classes. SRP serves as the foundation for layered architectures like MVC, Hexagonal, and Clean Arch.

• •SRP requires each class to have exactly one reason to change
• •Code examples show refactoring a God Class into focused single-responsibility classes
• •SRP underpins layered architectures like Clean Arch, MVC, and Hexagonal
