-- AppleScript --

-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.

-- Webkit variants include "Safari", "Webkit", "Orion".
-- Specific editions are valid, including "Safari Technology Preview".
-- "Safari" Example:
tell application "Safari" to return name of front document
