- Angular Signals simplify state management by removing the need for subscriptions and teardown logic.
- The CartService is extended with capabilities like removing items, clearing the cart, and tracking product count.
- Signals provide a single source of truth, eliminating the need for manual state synchronization.
- The update() function in signals allows for safe and expressive state transitions.
- Computed signals like total and totalCount automatically update when dependencies change.
- Components can consume signals directly without RxJS or async pipes, improving performance.
- Signals enhance testability by being synchronous and requiring no teardown logic.
- Signal-based services are scalable and ready for advanced features like discounts and inventory checks.
- Future articles will cover side effects, reactivity chaining, and advanced computed logic.
