Help translating from Python to JS

[Manuel Di Cristo]

Hey guys, I need to translate this python file into a javascript file using the NodObjC - If anyone can help I'd very much appreciate it!

from AppKit import NSApplication, NSApp
from Foundation import NSObject, NSLog
from Cocoa import NSEvent, NSKeyDownMask
from PyObjCTools import AppHelper

class AppDelegate(NSObject):
    def applicationDidFinishLaunching_(self, notification):
        mask = NSKeyDownMask
        NSEvent.addGlobalMonitorForEventsMatchingMask_handler_(mask, handler)

def handler(event):
    try:
        NSLog(u"%@", event)
    except KeyboardInterrupt:
        AppHelper.stopEventLoop()

def main():
    app = NSApplication.sharedApplication()
    delegate = AppDelegate.alloc().init()
    NSApp().setDelegate_(delegate)
    AppHelper.runEventLoop()

if __name__ == '__main__':
    main()
