Angular Signals provide a new reactive programming model that offers fine-grained reactivity and automatic dependency tracking. This tutorial demonstrates building a countdown timer using writable signals for state, computed signals for derived values, and effects for side operations. Signals eliminate manual subscriptions, provide better performance than zone-based change detection, and create more predictable reactive applications compared to RxJS observables.
