Angular - Signals

You want to migrate a component that uses multiple observables combined with combineLatest to a signal-based approach. Which Angular feature helps you combine multiple signals reactively?

AUsing <code>computed()</code> to derive a signal from multiple signals

BUsing <code>signal.combine()</code> method

CUsing <code>signal.merge()</code> method

DUsing <code>signal.pipe()</code> method

Step-by-Step Solution

Solution:

Step 1: Recall signal composition methods
Angular provides computed() to create derived signals from other signals.
Step 2: Compare with observable combineLatest
combineLatest merges multiple observables; similarly, computed() reacts to multiple signals.
Final Answer:
Using computed() to derive a signal from multiple signals -> Option A
Quick Check:
Use computed() to combine signals = A [OK]

Quick Trick: Use computed() to combine multiple signals reactively [OK]

Common Mistakes:

Looking for non-existent signal.combine() method
Confusing merge or pipe methods with signals
Trying to use combineLatest with signals
