Angular Signals vs Observables: A Deep Dive into Modern Reactivity

With the release of Angular 16, the framework introduced a powerful new reactive primitive: signals. Signals provide a new way to manage reactivity in your applications, enabling more predictable and efficient UI updates. But how do they compare with the well-established observables? When should you use one over the other? And how do features like computed() come into play? In this post, we’ll explore Angular signals in depth, compare them with observables, and provide practical use cases to guide your decision-making.
