How to access the node being traversed in the YUI tree

Question

I have created a tree data structure using YUI 3's tree.

I can traverse the tree can call a callback function.

I cannot figure out how to access the node being traversed from inside the callback function.

FWIW, I am new to YUI.

Any help is greatly appreciated.

The node that you're currently traversing will be passed in as the first parameter in the callback function. For example:

var tree = new Y.Tree({
    nodes: [
        /* Add your nodes here */
    ]
});

var root = tree.rootNode;

tree.traverseNode(root, function (node) {
    /* `node` will be the currently traversed node */
    console.log(node);
});

Here's an JSBin with working code, if you're still having any trouble getting this to work:
