Applying SOLID principles to TypeScript

The SOLID principles, formulated to enhance the readability, adaptability, extensibility, and maintainability of object-oriented designs, are essential guidelines for creating robust software. Originating from Robert C. Martin's 2000 work "Design Principles and Design Patterns" and popularized by Michael Feathers, SOLID stands for Single-responsibility, Open-closed, Liskov substitution, Interface segregation, and Dependency inversion principles. Each principle plays a unique role: ensuring classes have only one responsibility, allowing extensions without altering existing code, enabling subclasses to replace parent classes without issues, promoting smaller and more specific interfaces, and decoupling high-level modules from low-level modules through abstractions. Illustrated with TypeScript examples, these principles help developers write cleaner, more maintainable code, ultimately facilitating the growth of the codebase without negatively impacting other areas of the application.
