Converting to MathJax from jsMath
*********************************
MathJax is the successor to the popular `jsMath
`_ package for rendering
mathematics in web pages. Like jsMath, MathJax works by locating and
processing the mathematics within the webpage once it has been loaded
in the browser by a user viewing your web pages. If you are using
jsMath with its ``tex2math`` preprocessor, then switching to MathJax
should be easy, and is simply a matter of configuring MathJax
appropriately. See the section on :ref:`Configuring MathJax
` for details about loading and configuring MathJax.
On the other hand, if you are using jsMath's ``...`` and ``...

`` tags to
mark the mathematics in your document, then you should use MathJax's
``jsMath2jax`` preprocessor when you switch to MathJax. To do this,
include ``"jsMath2jax.js"`` in the `extensions` array of your
configuration, with the `jax` array set to include ``"input/TeX"``.
.. code-block:: javascript
extensions: ["jsMath2jax.js"],
jax: ["input/TeX", ...]
There are a few configuration options for ``jsMath2jax``, which you
can find in the ``config/MathJax.js`` file, or in the :ref:`jsMath
configuration options ` section.
