2.8 Handlers, subroutines and functions
Subroutines, or handlers (in AppleScript) and functions (in JavaScript), are scripting modules
you can refer to from within your script. These subroutines provide a way to re-use parts of
scripts. Typically, you send one or more values to a subroutine and it returns one or more
values.
There’s nothing special about the code used in subroutines — they are conveniences that save
you from having to retype the same code lines in your script.
