## What it is
Tangle is a JavaScript library for creating reactive documents where readers can interactively adjust variables and see the text update immediately. It lets authors write normal HTML/CSS with special data attributes plus a small JavaScript model to define how variables are computed.

## Use cases
- create interactive explorable explanations
- let readers play with parameters in an article
- build reactive essays with adjustable numbers
- embed live calculations in web documents
- make interactive tutorials with HTML and CSS
- visualize how changing inputs affects results inline

## When to choose
- you want Bret Victor-style explorable explanations in a plain HTML page
- you need a tiny, dependency-light way to bind variables to document text
- you're writing educational content with interactive parameters

## When to avoid
- you need a modern maintained framework with active support
- you're building a full web application rather than a document
- you need TypeScript, tooling, or npm ecosystem integration

## Facets
- artifact type: library
- maturity: abandoned
- function: state-management, templating
- domain: web-development, frontend, education, data-visualization
- platform: browser
- tags: reactive-documents, explorable-explanations, interactive-writing, data-binding, javascript
