Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Binary Search Tree (BST) Implementation

This repository contains a JavaScript implementation of a Binary Search Tree (BST), providing foundational tree operations like insertion, deletion, searching, and traversal. The project supports traversal methods including in-order, pre-order, post-order, and level-order, along with balance checking and rebalancing.

Installation

npm install @tekksunn/cs-hashmap

Features

  • insert(value) - Adds a new node to the BST while maintaining order.
  • deleteItem(value) - Removes a node by value, handling cases with no children, one child, or two children.
  • find(value) - Locates and retrieves a node based on its value.
  • levelOrder(callback) - Traverses the tree in breadth-first level order, calling the provided callback function on each node.
  • inOrder(callback) - Traverses the tree in in-order sequence (left-root-right) and calls the provided callback function on each node.
  • preOrder(callback) - Traverses the tree in pre-order sequence (root-left-right) and calls the provided callback function on each node.
  • postOrder(callback) - Traverses the tree in post-order sequence (left-right-root) and calls the provided callback function on each node.
  • height(node) - Calculates and returns the height of the given node.
  • depth(node) - Calculates and returns the depth of the given node relative to the tree’s root.
  • isBalanced() - Checks if the tree is balanced.
  • rebalance() - Rebalances the tree when it becomes unbalanced.
  • prettyPrint() - Visualizes the tree structure in a console-friendly format.
