in a similar way to the \Pkg{luaotfload} package:
\begin{itemize}
\item Cache files are usually stored in (and loaded from)
\item We cannot share same binary cache for \LuaTeX\ and LuaJIT\TeX.
Hence we distinguish them by their extension, ``\texttt{.luc}'' for \LuaTeX\
and ``\texttt{.lub}'' for LuaJIT\TeX.

\subsection{Internal}
Cache management system of \LuaTeX-ja is stored in \texttt{luatexja.base}
(\texttt{ltj-base.lua}).
-There are three public functions for cache management in \texttt{luatexja.base},
