Angular developers are encouraged to reconsider their approach to handling API calls and explore the use of Signals over subscriptions.Using Signals in Angular allows for automatic subscription management, reduced boilerplate code, and more declarative and efficient code.Developers need to be cautious of common mistakes when using Signals, such as forgetting to set the initial value and not handling error properly.Signals are intended for state management and not meant to replace all observables or other mechanisms in Angular.
