I'll first explain what this code does step-by-step and then address your question about whether it is written correctly.

Explanation:

1. Module Script (First Part):

• This portion defines a Lua module script that provides a function for adding two numbers.

local module = {}
function module.add(a, b)
  local result = a + b
  return result
end
return module

• A table named module is created.
• The function add is added to this table, which takes two arguments a and b, adds them together (a + b), and returns the result.
• Finally, the module returns itself (return module), making it externally accessible when required in other scripts.

2. Server Script (Second Part):

local SSS = game:GetService("ServerScriptStorage")
local module = SSS:WaitForChild("moduleScript")
local moduleTable = require(module)
print(module.add(4, 6))

• The script is intended to be a server-side script in Roblox.
• game:GetService("ServerScriptStorage") retrieves the ServerScriptStorage service of the game. This is where server-side scripts/modules are typically stored.
• WaitForChild("moduleScript") looks for a child object named moduleScript inside ServerScriptStorage and waits for it to exist. Presumably, moduleScript is the ModuleScript containing the module code defined earlier.
• require(module) loads and returns the table from the module script, which is assigned to the variable moduleTable.
• Finally, it calls the add function from the module with 4 and 6 as arguments, producing the result 10, which is then printed to the output using print.

Output:

• The output of the script will be:

10

Is Your Code Correct?

Your code has a small issue: the line print(module.add(4, 6)) should actually be print(moduleTable.add(4, 6)).

This is because the function add is a part of the required module table (moduleTable), not the module variable. In your server script, module is the reference to the ModuleScript instance, not the table returned by require().

Corrected Server Script:

local SSS = game:GetService("ServerScriptStorage")
local module = SSS:WaitForChild("moduleScript")
local moduleTable = require(module)
print(moduleTable.add(4, 6)) -- Correctly calling the function from the required table

Once this correction is made, the code will work as intended and print 10 to the output.
