Angular Signals are a new reactive primitive in Angular that simplify state management and offer direct access to updated values.There are two types of signals: Writable Signals (for updating values) and Computed Signals (derive value from other signals).A simple counter example demonstrates the usage of a writable signal in Angular.Benefits of using signals include simplicity, performance improvement, and reduced boilerplate code.To set up an Angular environment for using signals, ensure you have Angular 16+ installed.Signals can be implemented in components using writable signals for direct state updates.Computed signals allow deriving values based on other signals, providing enhanced functionality.Best practices for signals include avoiding direct mutations and handling computed signals carefully.If transitioning from RxJS, use Angular's toSignal and toObservable utilities gradually to mix signals with observables.Angular Signals offer a simple yet powerful way to handle state and reactivity in Angular applications, improving development experience.
