# 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 Configuring MathJax for details about loading and configuring MathJax.

On the other hand, if you are using jsMath’s `<span class="math">...</span>` and `<div class="math">...</div>` 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"`.

    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 jsMath configuration options section.
