- you want a free online reference for RxJS operators
- you prefer book-style documentation over API docs

## When to avoid
- you need official or up-to-date RxJS API documentation
- you work with reactive libraries in other languages
- you need an executable tool rather than reading material

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