Really not sure what the point of either of these would be, could you fill in more of a real word example?
ObjC.import('Cocoa')
And then you get stuff like
task = $.NSTask.alloc.init task.running == task.isRunning
The AppleScript version
if application "iTunes" is running then --- Do stuff... end if
It may just be me, but in some cases the AppleScript version is easier and better.
Mail = Application('Mail')
if (Mail.isRunning) { ... }
