/* Using a Local File for Configuration
Using a Local File for Configuration
If you are using the same MathJax configuration over multiple pages,
you may find it convenient to store your configuration
in a separate JavaScript file that you load into the page.
For example, you could create a file called mathjax-config.js that contains
window.MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']],
},
svg: {
fontCache: 'global'
}
};
and then use
<script src="mathjax-config.js" defer></script>
<script type="text/javascript" id="MathJax-script" defer
src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js">
</script>
to first load your configuration file,
and then load the tex-svg component from the jsdelivr CDN.
Note that here we use the defer attribute on both scripts
so that they will execute in order,
but still not block the rest of the page
while the files are being downloaded to the browser.
If the async attribute were used,
there is no guarantee that the configuration would run first,
and so you could get instances
where MathJax doesn't get properly configured,
and they would seem to occur randomly.
