I created intercooler.js in 2013 so I could do AJAX in HTML:
Last year I removed the jquery dependency and cleaned it up based on a lot of lessons that I learned, renaming it to hmtx:
Same idea: extends/complete HTML as a hypertext so you can build more advanced UI within the original hypermedia web model, with a cleaner implementation.
Part of that cleanup involved me pulling out some functionality around events and a proto-scripting language (ic-action), and I enjoy programming languages, so I created a front end scripting language to fill that need:
It's based on HyperTalk and has a lot of domain specific features for lightweight front end scripting, kind of a jQuery or AlpineJS alternative.
