One day I want to learn backbone.js since I think it’s a front-end framework to do facebook-ey ajax-ey stuff. Or maybe even marionette which seems to be … I dunno, more than backbone… this site might help.
There is also Mithrill … but I don’t know if it’s really the same sort of thing.
But perhaps that should come after I get a basic server-side thing working first. 🙂
