How to define a parameters type in a function? (Lua)

Question

Hi, I'm recently trying to make a module for my Lua script, and I was curious on how to define a functions parameter type for example

function test(Param1: string, Param2: function)
print(Param1)
Param2()
end

test("string", function ()
print("Callback function")
end)

I want the function to only be able to run a parameter that is a string and not an int and run a parameter that is a function which indicates the callback. Code example above.

Alright, so I've came up with a solution I'm just gonna add block comments inside of the function
For example:

function test(Param1 --[[string]], Param2 --[[function]])
print(Param1)
Param2()
end

test("string", function()
print("string")
end)

Comments don't do much, but this is just giving my function some details so I know which is a function and which is a string.
It's not a permanent solution, but it's okay.
