Where to save applescripts for apps?

I'm an old Applescript hack from WAAAAY back, LOL. Anyway, I know that at some point they changed the way you reference application names in the Application Scripts folder from "iTunes" to "com.apple.iTunes." But just now I asked to make iTunes scriptable in MacOS 10.13 and it created a folder called "iTunes" in a folder called "Applications" in "~/Library/Scripts." So now I'm confused. Is it "~/Library/Scripts/Applications" or "~/Library/Application Scripts?" and if the system created a folder called "iTunes" then why do I have folders with fully qualified app names (like "com.apple.iTunes") in "Application Scripts?" What gives? Where am I supposed to put user scripts?

Any light you can shed on this would be appreciated.
