Introduction

LaTeX A TEX-based typesetting system suitable for producing scientific, mathematical, and physical documents of high print quality.

LaTeX official website (latex-project.org)
KaTeX official website (katex.org)

And KaTeX handles only a smaller subset of LaTeX's mathematical notation for display on the web
