The only JavaScript is in the Electron process, and it's fixed, ie you don't have to touch it. You interact with it through CLOS methods on window objects.
Other than that any JavaScript is optional, you write it yourself (using whatever source language, e.g. ParenScript) and ship it with your app as a resource.

The gist is: for the Javascript parts on your site, any plans to integrate Parenscript for the full Lisp experience?
Thanks for your work. I saw again it was posted before today on /r/lisp and /r/programming, but I missed it.
