kwargs allows users to pass arbitrary information into a Node that

For example, users may want to pass "attr" or some other valid jsTree options.
Example:
>>> from dictobj import *
>>> node = Node('a', None)
>>> node._items == {'text': 'a', 'children': MutableDictionaryObject({})}
True
>>> node.jsonData() == {'text': 'a'}
True
>>> import jstree
