This TypeScript library is the main part of a more powerfull package designed for the fast WEB software development. The cornerstone of the library is the **DataStore** class, which might be useful when you need a full control of the data, but do not need

import { BinarySearchTree } from "./BinarySearchTree";
import { Element } from "../Collection";
import { BinaryTreeNode } from "./BinaryTreeNode";
/**
 * In computer science, an `AVL tree` (named after inventors Adelson-Velsky and Landis) is a
 * self-balancing binary search tree. It was the first such data structure to be invented.
 * In an AVL tree, the heights of the two child subtrees of any node differ by at most one;
 * if at any time they differ by more than one, rebalancing is done to restore this property.
 * Lookup, insertion, and deletion all take O(log n) time in both the average and worst cases,
 * where n is the number of nodes in the tree prior to the operation. Insertions and deletions
 * may require the tree to be rebalanced by one or more tree rotations.
