An implementation of WCS functionality in JavaScript would be useful for helioviewer.org. Passing WCS information to the browser would allow more precise location of features and events, and calculation of position more generally. Such a library would also be useful for astrophysical applications in the browser, as well as other existing solar physics web applications such as Solar Monitor.
This page:
https://www.atnf.csiro.au/people/mcalabre/WCS/wcslib/software.html
lists implementations of WCS. There is an existing WCS implementation in JavaScript:
https://github.com/astrojs/wcsjs
but it is about 10 years old. The source WCSlib has been updated, and Emscripten has been updated, since 10 years ago, so the JavaScript version of WCS should also be updated.
