What is Multicasting?
Multicasting allows an observable to share its execution across multiple subscribers, so that all subscribers receive the same emitted data at the same time. By default, observables in RxJS are βunicast,β meaning each subscription creates a separate execution of the observable. This can lead to multiple API calls or side effects if several components subscribe to the same observable.
Multicasting ensures that only one execution occurs, regardless of how many subscribers are attached to the observable. This is particularly useful in scenarios where expensive operations (such as HTTP requests) should be shared across multiple components without being re-executed multiple times.

Places Where We Can Use Dynamic Module Loading
β Micro-Frontends: When integrating multiple micro-frontends, each built with different versions of Angular or other frameworks, dynamic module loading can help load and compile modules based on the frontend in use.
β Third-Party Integrations: If your application needs to integrate third-party Angular libraries or components dynamically at runtime, dynamic loading can optimize their performance and only include the necessary code.
β Role-Based Access Control (RBAC): Dynamic module loading is excellent for conditionally loading parts of the application based on the userβs role or permissions. You can securely avoid loading unnecessary modules for users with restricted access.
