Building Flexible Systems with TypeScript Polymorphism

This guide demonstrates how to leverage TypeScript's type system to implement inheritance and polymorphism patterns that create flexible, extensible systems. By using abstract classes and type hierarchies, developers can write code where implementations can vary without affecting client code—enabling cleaner, more maintainable architectures. The type safety provided by TypeScript ensures polymorphic behavior is validated at compile time rather than discovered at runtime, reducing bugs in production systems.
