## What it is
A source code bundle for the book 'Learning JavaScript Data Structures and Algorithms', containing JavaScript and TypeScript implementations of classic data structures and algorithms. It is organized by book chapter and includes Jest test cases for educational purposes.

## Use cases
- learn data structures in javascript
- study algorithms with typescript examples
- find reference implementations of linked lists, trees, and graphs
- practice with sorting and graph algorithms like dijkstra
- companion code for the javascript data structures and algorithms book

## When to choose
- you are learning data structures and algorithms from scratch in JavaScript or TypeScript
- you want readable, well-tested educational implementations to study alongside the book
- you need simple reference code for stacks, queues, trees, or graph algorithms

## When to avoid
- you need a production-grade, performance-optimized algorithms library
- you need data structures for a real application rather than learning
- you work outside the JavaScript/TypeScript ecosystem

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: education, programming-languages, tutorials
- platform: cross-platform
- tags: data-structures, algorithms, javascript, typescript, book-companion, jest-tests, educational, nodejs
