## What it is
A Chinese-language learning resource with notes, documentation, and test code for learning JavaScript data structures and algorithms from scratch. It accompanies a Bilibili video course and is published as an online docs site.

## Use cases
- learn data structures in javascript
- study algorithms for coding interviews
- find javascript examples of linked lists and trees
- review sorting and searching algorithms
- beginner-friendly data structure tutorial with code

## When to choose
- you are a JavaScript developer starting from zero with DS&A
- you want notes paired with a video course and runnable test code

## When to avoid
- you need a production data-structures library to import
- you need English-language material or a non-JavaScript language

## Facets
- artifact type: learning-resource
- maturity: stable
- function: developer-tools
- domain: tutorials, programming-languages
- platform: -
- tags: data-structures, algorithms, javascript, study-notes, interview-prep, documentation, nodejs
