## What it is
A curated learning resource offering clear, executable examples and explanations for RxJS operators, subjects, and reactive programming concepts. It supplements the official RxJS documentation with approachable tutorials, recipes, and links to the best related material on the web.

## Use cases
- learn rxjs from scratch
- understand rxjs operators with examples
- how do observables work in javascript
- difference between subject behaviorsubject and replaysubject
- reactive programming tutorial for javascript
- error handling with rxjs operators
- convert imperative code to declarative streams

## When to choose
- you are learning RxJS or reactive programming for the first time
- you need clear, runnable examples for a specific RxJS operator
- you want curated external resources and recipes beyond the official docs

## When to avoid
- you need official API reference documentation rather than tutorials
- you are looking for a runnable RxJS library itself rather than learning material
- you need reactive programming resources for a non-JavaScript language

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: web-development, frontend, tutorials, programming-languages
- platform: browser, cross-platform
- tags: rxjs, reactive-programming, observables, javascript, typescript, async, nodejs
