Creating a BinaryTree using Javascript

Let us understand how we're going to create and represent a binary search tree in Javascript. We'll first need to create the class BinarySearchTree and define a property Node on it. 

Example

class BinarySearchTree {
   constructor() {
      // Initialize a root element to null.
      this.root = null;
   }
}

BinarySearchTree.prototype.Node = class {
   constructor(data, left = null, right = null) {
      this.data = data;
      this.left = left;
      this.right = right;
   }
};

We've simply created a class representation of our BST class. We'll fill this class in as we proceed to learn functions that we'll add to this structure.
