Many of the functions we used to use jQuery for are now built into most
browsers from the last 10 years.

By far the most common are element selectors like:

  var panel = $('#header-panel')
  var arrow = $('.arrow')

which we just change to:

  var panel = document.querySelector('#header-panel')
  var arrow = document.querySelector('.arrow')

This is all vanilla JavaScript in individual files imported via <script>
without any sort of compilation process. This seems to be the simplest
path to get into distributions like Guix and Debian. The main problem
with purescript and others is that they require more dependencies, build
steps and tooling and are known by less people.

We have a few dependencies which will be harder to deal with such as the
video, audio and 3D model viewers. In the first instance, I think the
answer will be to do without this JavaScript entirely. That should be
feasible for video and audio given modern browser support. Perhaps we
don't ship 3D model support out of the box in distros for now.

Regards,
Ben
