Folder Actions are defined in Standard Additions. The full syntax for this action is:

on adding folder items to this_folder after receiving added_items

You JXA script should look something like this:

app = Application.currentApplication()
app.includeStandardAdditions = true

function addingFolderItemsTo(this_folder, {afterReceiving:added_items})
{
    app.beep(2)
   // your code here uses this_folder and/or added_items
}

Parameters:

this_folder is an alias to the receiving folder.

added_items is a list of aliases for the dropped items.
