\maketitle
\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
in 1984 by Leslie Lamport and has become the dominant method for
using \TeX;
% This is a comment, not shown in final output.
% The following shows typesetting power of LaTeX:
\begin{align}
E_0 &= mc^2 \\
E &= \frac{mc^2}{\sqrt{1-\frac{v^2}{c^2}}}
\end{align}
\TeX{}live.js even supports images! This photo was taken by Laura Poitras/Praxis Films
