local function greet(name)
    print("Hello, " .. name)
end

io.write("Your name: ")
local input = io.read()
greet(input)

Sample differences (any three or more):

1. The Lua version reads input from the keyboard with io.read().
   The Luau version receives the name from a Roblox event
   (Players.PlayerAdded).
2. The Lua version calls greet(input) directly. The Luau version
   passes greet into :Connect, so the engine calls it later when
   the event fires -- once per joining player.
3. The Luau version uses game:GetService("Players") to find the
   Players service. Standalone Lua has no `game` and no services.
4. The Luau version reads `player.Name` -- a property of an
   Instance. Standalone Lua has no Instances.
5. print() in plain Lua writes to the terminal. In Roblox it writes
   to the Output panel inside Studio.
