Angular - Signals

How does Angular's signal mechanism differ from observables in terms of change detection?

ASignals trigger synchronous updates immediately upon value change.

BObservables always emit values synchronously without delay.

CSignals require manual subscription to receive updates.

DObservables cannot be used for reactive programming.

Step-by-Step Solution

Solution:

Step 1: Understand signals
Signals in Angular update their value synchronously and notify dependents immediately.
Step 2: Understand observables
Observables can emit values asynchronously and require subscriptions to receive updates.
Final Answer:
Signals trigger synchronous updates immediately upon value change. -> Option A
Quick Check:
Signals update synchronously, observables can be async. [OK]

Quick Trick: Signals update synchronously; observables can be async. [OK]
