Function onDeepChange

onDeepChange(node: object, listener: NodeChangeListener): Dispose
Registers a deep change listener on the provided node.

The listener is invoked whenever the node undergoes a change, such as additions, updates, or removals within its observable structure. This includes receiving events from both object and array mutations.
Parameters
- node: object
  The node to attach the change listener to.
- listener: NodeChangeListener
  The callback function that is called when a change occurs. The listener receives two parameters:
  
  changeTarget: The node where the change occurred.
  
  change: The change event, which is a NodeChange.
Returns Dispose
A disposer function that, when invoked, unregisters the listener.
