$splitNode
to thrown if called on rootIt's possible to keep
$splitNode
working with root. E.g., if we have root with 2 children, and trying to call$splitNode(root, 1)
, it'll return[firstRootChild, secondRootChild]
without modifying (splitting) the tree. But then it means those children might be elements or decorators, so it would require API call site to check return type. Plus, there's no guarantee that there will be left or/and right tree at all since root can be empty. Supporting all of these will make$splitNode
return type too vague ([null | ElementNode | DecoratorNode, null | ElementNode | DecoratorNode]
) and it seems easier to handle root separately instead$insertNodeToNearestRoot
