-It also acts as a Suspense boundary, rendering a fallback element until the

+mounted, and will unsubscribe from all of them once it unmounts.

 ```tsx

 #### Properties
 
-- `source$`: Source Observable that the Component will subscribe to.
+- `source$`: (Optional) Source Observable that the Component should subscribe to, before its children renders.
 - `fallback`: (Optional) The JSX Element to be rendered before the
   subscription is created. Default: `null`.
