What is a module script and what does it do?

[mohammedabergsson31 (red_fish)]

Hello there! I have just discovered a new script called module script, and i was curious on what it does.
Ik that regular scripts are used objects, instances and services and more.
Ik that local scripts are used for clients.
However idk what module scripts are used for.
And of course i searched on the developer hub, but im still not getting it.

How do I use ModuleScripts?

Documentation for ModuleScripts is available on the Developer Hub, which is where you should begin your search first before asking here. The difference between searching first is that you’d be asking questions on how to utilise or understand parts of a ModuleScript over asking how to do something pre-explained. There’s many different ways in which you can utilise a ModuleScript to determine functions for usage. The point of a ModuleScript is that while it does run code like a regular script on …

Here’s an old response I wrote on a similar topic.

Modulescripts are scripts that can be ran and used by other scripts and localscripts through the require function, when required they can return a value, similarly to functions, except it can only return a single value.

Example:

--Modulescript

local foo = "bar"

return foo

--Script

print(require(workspace.ModuleScript))
-- bar

If you want to return many values use tables
–Module script

local table = {true,13,"Hi",game.Workspace}

return table 

–Normal script

local theTable = require(TheModuleScript)
local hi = theTable[3]
local theNumber = theTable[2]
print(hi,theNumber) -- hi13
