    print("Hello, " .. Player.Name .. "!")
end)

HelloPlayer:Connect(function(Player)
    print("Hello, " .. Player.DisplayName.. "!")
end)

game.Players.PlayerAdded:Connect(function(Player)
    HelloPlayer:FireAsync(Player) -- Hello, Username!, Hello, DisplayName!
end)

Once Example:

local PromisedSignal = require(game.Path.To.PromisedSignal)
local HelloPlayer = PromisedSignal.new()

HelloPlayer:Once(function(Player)
    print("Hello, " .. Player.Name .. "!")
end)
