Code (This is heading title style)

Since every tree contains nodes, which can be a separate constructor from a tree, we will outline the operations of both constructors: Node and Tree.

Heading 02

_root points to the root node of a tree.
traverseDF(callback) traverses nodes of a tree with DFS.
traverseBF(callback) points to the next node in the list.
contains(data, traversal) searches for a node in a tree.
add(data, toData, traverse) adds a node to a tree.
remove(child, parent) removes a node in a tree.

This is sub-heading title style

Now let’s write the code for a tree!

This is third-heading title style

For our implementation, we will first define a function named Node and then a constructor named Tree.

function Node(data) {
	this.data = data;
	this.parent = null;
	this.childen = [];
}
						

This is third-heading title style

For our implementation, we will first define a function named Node and then a constructor named Tree.

Tree.prototype.traverseDF = function(callback) {

    // this is a recurse and immediately-invoking function
    (function recurse(currentNode) {
        // step 2
        for (var i = 0, length = currentNode.children.length; i < length; i++) {
            // step 3
            recurse(currentNode.children[i]);
        }

        // step 4
        callback(currentNode);

        // step 1
    })(this._root);

};
