Yes I meant writing a Javascript application that runs within a browser context. It's perfectly doable for anything that would otherwise be done with a language like Arexx (excluding the use of application ports, however).
You can write all sorts of useful calculation tools and stuff that simply run scripts in a browser window. All the input can be handled via forms and so on.
As long as you dont start using css and stuff, your application would thus run most places, amiga included.
