Reactive programming using Angular Signals
We briefly discussed Angular Signals in Chapter 2, but let’s reiterate that and dive a bit deeper so that you can get a good grasp of Angular Signals and how they can help you handle code more reactively.
Angular Signals was introduced in Angular 16, and it’s one of the most significant changes for the framework since it went from AngularJS to Angular. With Signals, the Angular framework now has a reactive primitive in the Angular framework that allows you to declare, compute, mutate, and consume synchronous values reactively. A reactive primitive is an immutable value that alerts consumers when the primitive is set with a new value. Because all consumers are notified, the consumers can automatically track and react to changes in this reactive primitive.
Because Signals are reactive primitives, the Angular framework can better detect changes and optimize rendering, resulting in better performance. Signals are the first...
