## What it is
A collection of JavaScript and Node.js cheatsheets covering Express.js, MongoDB/Mongoose, React, ES6, JavaScript, and Node.js/npm, available both as online HTML pages and downloadable PDFs. It is a reference resource maintained by author Azat Mardan rather than a software tool.

## Use cases
- quickly look up Express.js 4 API syntax while building a web app
- find a concise MongoDB and Mongoose query reference
- review ES6 features like arrow functions and destructuring
- get a printable PDF cheatsheet for React.js
- brush up on Node.js core concepts like the event loop and streams
- keep a quick JavaScript language reference handy while coding

## When to choose
- you want concise, printable or online quick-reference sheets for JavaScript, Node.js, Express, React, or MongoDB
- you are learning these technologies and need a compact summary of key APIs and syntax
- you prefer PDF cheatsheets to keep offline or print

## When to avoid
- you need comprehensive, up-to-date documentation for the latest versions of these frameworks
- you need an interactive tutorial or runnable code examples rather than a static reference
- you need a software library or tool to include in a project

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: web-development, developer-tools, tutorials
- platform: cross-platform
