Pipe JS from a file in terminal to be executed in Chrome via AppleScript

jsChrome.scpt

(* Save this script as (e.g.) jsChrome.scpt and run it as follows
in a terminal:

 osascript jsChrome.scpt someJSFile.js

The content of someJSFile.js will now be run in the active tab of 
what is considered your "window 1" of a running Chrome instance.

If this is your first time running JavaScript in Google Chrome from
AppleScript, you will need to enable this in 
  View -> Developer -> Enable JavaScript from Apple events

Combinate this with e.g. nodemon to get JS run in a Chrome tab on 
file save.
