## What it is
The WHATWG Streams Standard, a living web specification defining APIs for creating, composing, and consuming streams of data (readable, writable, and transform streams). The repository hosts the spec text, tests, and a JavaScript reference implementation.

## Use cases
- understand how ReadableStream and WritableStream work in the browser
- look up the spec behavior of stream backpressure and piping
- implement streams APIs in a JavaScript runtime
- contribute fixes or clarifications to the Streams Standard
- learn how fetch response bodies expose streams
- check normative requirements for transform streams

## When to choose
- you need the authoritative definition of web stream APIs
- you are implementing streams in a JS engine or runtime
- you want to contribute to or track the web streams spec

## When to avoid
- you want a ready-made library for stream processing rather than a specification
- you need Node.js-specific stream documentation
- you want tutorials rather than normative spec text

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: web-development, apis, documentation
- platform: browser
