Create a new tree node and set its value and optionally user data.

Constructor

class Node([value][, data])

Invokes a callback for the node and all its child nodes in preorder (document order).

forEachDescendant

Node#forEachDescendant(callback[, T])

Arguments:

• callback (function) – The function which will be invoked for each node.
• T (object) – Context object bound to “this” when the callback is invoked.

forEachPostorder

Node#forEachPostorder(callback[, T])

Arguments:

• callback (function) – The function which will be invoked for each node.
• T (object) – Context object bound to “this” when the callback is invoked.
