## What it is
A slide-deck and code repository by Azat Mardan introducing core Node.js features such as the event loop, non-blocking I/O, event emitters, streams, buffers, clusters, and C++ addons. It accompanies a talk and blog essay in the style of the 'You Don't Know JS' series.

## Use cases

- you want a comprehensive, maintained book or course
- you need a reference for modern async patterns like async/await

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