## What it is
An educational repository containing super simplified implementations of common data structures written in heavily commented, easy-to-read JavaScript. It serves as a guided code walkthrough to teach what data structures are, their uses, and how to discuss them.

## Use cases
- learn data structures from scratch
- understand how linked lists and stacks work
- prepare for coding interviews on data structures
- read annotated code explaining computer science concepts
- find a beginner-friendly introduction to data structures

## When to choose
- you are a beginner learning data structures for the first time
- you prefer learning by reading guided, annotated source code
- you want a quick refresher on common data structure concepts in JavaScript

## When to avoid
- you need production-ready, performant data structure implementations
- you need comprehensive coverage of advanced data structures
- you need a maintained library with active development and releases

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, tutorials, programming-languages
- platform: -
- tags: data-structures, educational, annotated-code, computer-science, beginner-friendly, algorithms, javascript, nodejs
