Javascript Depth-first Search

I am trying to implement DFS in JavaScript but I am having a little problem. Here is my Algorithm class: 'use strict'; define([], function () { return function () {

Solution 1:

The problem is your addChild() method only expects one parameter, but you are passing in multiple nodes to it.

Change your calling code to:

node1.addChild(node2);
node1.addChild(node7);
node1.addChild(node8);

node2.addChild(node3);
node2.addChild(node6);

node3.addChild(node4);
node3.addChild(node5);

node8.addChild(node9);
node8.addChild(node12);

node9.addChild(node10);
node9.addChild(node11);

Or you can change addChild to accept multiple children (probably want to change the name too):

this.addChildren = function () {
    for (var i = 0; i < arguments.length; i++) {
        children.push(arguments[i]);
    }
};
