## What it is
An interactive web-based edition of Structure and Interpretation of Computer Programs (SICP) where nearly every code fragment can be edited and re-run in the browser via an embedded Scheme interpreter. It combines the classic MIT textbook with CodeMirror editors and exercise autograders.

## Use cases
- learn SICP interactively in the browser
- study structure and interpretation of computer programs online
- run scheme code examples from SICP without installing anything
- work through SICP exercises with autograding
- teach an introductory computer science course using SICP

## When to choose
- you want to read SICP with runnable, editable code examples
- you prefer a hands-on textbook experience with zero setup
- you are self-studying Scheme and functional programming fundamentals

## When to avoid
- you need a completed, polished edition - the project is a work-in-progress with chapters still being ported
- you need offline access or a printable textbook
- you want a modern JavaScript or Python introduction rather than Scheme

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: interpreter, editor, documentation
- domain: education, programming-languages, tutorials
- platform: browser
- tags: sicp, interactive-textbook, scheme, lisp, computer-science, online-book, web-server, javascript
