Invokes a callback for each child of the given node. The 'cbNode' callback is invoked for all child nodes stored in properties. If a 'cbNodes' callback is specified, it is invoked for embedded arrays; otherwise, embedded arrays are flattened and the 'cbNode' callback is invoked for each element. If a callback returns a truthy value, iteration stops and that value is returned. Otherwise, undefined is returned.
