Type Less, Discover More: Building Self-Contained Objects in Angular

Building enterprise Angular applications often starts with the same pattern: fetching raw data objects from a REST API and storing them directly in application state.

However, as applications grow, treating state as passive data containers causes business logic to bleed across components, pipes, and utility files.
