## What it is
A hand-deobfuscated and annotated version of an old JSLinux x86 emulator written in JavaScript, made readable for study. It runs Linux in the browser and serves as a pedagogical resource for understanding in-browser x86 emulation.

## Use cases
- study how an x86 emulator works in javascript
- run linux in the browser
- learn cpu emulation internals
- read annotated jslinux source code
- hack on in-browser x86 emulation

## When to choose
- you want to study Fabrice Bellard's original JSLinux code in readable form
- you need a simple browser-based x86 emulator to experiment with
- you're learning how opcode execution loops and CPU emulation work

## When to avoid
- you need a modern, maintained x86 emulator (use v86 instead)
- you need current JSLinux features or emscripten-based performance
- commercial use or redistribution matters - the license prohibits both without permission

## Facets
- artifact type: application
- maturity: maintenance
- function: simulation, interpreter, developer-tools
- domain: operating-systems, developer-tools, education
- platform: browser
- tags: x86-emulator, jslinux, deobfuscated, virtualization, pedagogical, algorithms, javascript, web-server
