Here is the input code:

  var newTree = {};
  newTree.value = value;
  newTree.children = [] // fix me
  
  Object.assign(newTree, treeMethods)
  
  return newTree;
};

var treeMethods = {};

treeMethods.addChild = function(value) {
    const newNode = Tree(value);
    this.children.push(newNode)
};

treeMethods.contains = function(target) {
    let currentTree = this.children
    while (currentTree != null) {
        if (currentTree.indexOf(target) > -1) return true
        currentTree = this.children[target]
    }
    return false
    
}; 

I am trying to determine if, given a target value via the contains function, can I find the target value called to contains() in parent nodes or descendant nodes.

Please don't give me the full answer but if you could push me in the right direction.
