What are Smart and Dumb Components and why are they important?

Quick Answer Smart (Container) components: manage state, communicate with services, handle data fetching. Dumb (Presentational) components: receive data via @Input, emit events via @Output, no direct service dependencies. Benefits: dumb components are easily reusable, testable (just pass inputs and check outputs), and work naturally with OnPush (inputs are always explicit). Separation of concerns makes the app cleaner.

Answer

Smart Components handle data fetching, state management, and service interactions.

Dumb Components focus purely on presentation, using @Input and @Output. They are reusable, testable, and predictable.

This separation improves scalability and modularity in enterprise Angular applications.
