## Project history and usage

MuJS is an embeddable JavaScript interpreter in C developed and maintained by Artifex Software. The project site says it was originally developed for the MuPDF viewer, then made useful as an independent component. The GitHub mirror records Artifex copyright years beginning in 2013, and the public repository mirror was created in 2017.

### Project history

The interpreter is aimed at applications that need scripting without pulling in a large browser engine. Its introduction page emphasizes ES5 compliance, portable C, building from a single C file, a small footprint, a simple embedding API, and a default sandboxed build. The README presents the package as a lightweight interpreter for extending other software with scripting capabilities, with command-line interpreter, static library, and header installation targets.

### How it is used

In package-manager ecosystems, MuJS belongs with embeddable language runtimes such as Lua, Duktape, QuickJS, and JerryScript. Its distinguishing role is a small C implementation tied historically to the MuPDF and Ghostscript/Artifex family, suitable for projects that want JavaScript extension points without V8-scale dependencies.
