\TeX{}live.js is a compiler for the \TeX{}
typesetting program created using Mozilla's Emscripten
Compiler. It offers programmable desktop
publishing features and extensive facilities for
automating most aspects of typesetting and desktop
publishing, including numbering and cross-referencing,
tables and figures, page layout, bibliographies, and
much more. It supports \LaTeX{} which was originally written
