for example

local function uhh(argumentWhichIsSomethingToPrint)
      print(argumentWhichIsSomethingToPrint)
end

uhh("this is argument one")

Or you can send tables or parts or anything.

Some examples:

local function calculate(a, b) -- two arguments
	return a + b -- returning arguments
end

print(calculate(1, 10)) -- this func prints 11


-- Another


local function getUserId(player) -- one arguments
	return player.UserId
end

game.Players.PlayerAdded:Connect(function(plr)
	print(getUserId(plr)) -- print UserId of player
end)

if you were to make a function to clone a part, then you have a argument in that function named “Part” and you clone the argument and parent it.

When you call it, you do

ClonePartFunction(workspace.Part)

You can think of functions as a group of statements which perform a certain task with (optional) inputs, commonly known as parameters or arguments to a function.
When defining a function, you’re given the ability to define arguments (inputs) which will be later used in the function
For example:

--// no inputs/arguments defined
function myFunction()
end

--// one argument named "argument1" defined
function myNewFunction(argument1)
end

Now lets make another simple function which prints something to the console

function outputMessage(message)
    print(message)
end

outputMessage("Hello, World!") --// prints "Hello, World!" to the console
outputMessage("I am learning about function arguments!")

Let’s now create a function which calculates the circumference of a circle.

function circumference(radius)
    return 2 * radius * 3.14
end

circumference(3) --// radius is now equal to 3, will return 2 * 3 * 3.14 = 18.84
circumference(9) --// radius is now equal to 9, will return 2 * 9 * 3.14 = 56.52

you may think like its data tranfer.

local Calculator(a,b) --a and b are the values that requires to run the function
    return a + b --returns the result
end

print(Calculator(5,5)) --will print 10 because the function returned the result as 10 and we printed it.
