hard🧠 Conceptual Q10 of 15
Step-by-Step Solution
Solution:
Step 1: Define cold and hot observables
Cold observables start producing data when subscribed; hot observables produce data independently of subscriptions.Step 2: Understand why this matters
This affects how data is shared and when it is produced, impacting app behavior and resource use.Final Answer:
Because cold observables start emitting on subscription, hot observables emit regardless of subscribers. -> Option AQuick Check:
Cold vs hot observable difference = A [OK]
Quick Trick: Cold starts on subscribe; hot emits always. [OK]
Common Mistakes:
MISTAKES- Thinking hot observables cannot unsubscribe
- Assuming cold observables are synchronous only
- Believing hot observables complete immediately
