How to use this type of function with modules?

[stormmaster9090]

Hi guys, I was wondering how could I do this with my module scripts?
here is an example
in Topbarv3 it has this exact same function thing.

Ive looked for it online but couldnt really find anything?

local C = require(game.ReplicatedStorage.Icon)

C.set() is a constructor that creates an object that uses self. When you run the C.set():Option("1") line you basically do the following:

local object = C.set()
object.Option(object, "1") --self means that the object itself is passed as first arg
--this is hidden through the use of the : symbol when calling the function

For organization there’s a chance that set is a submodule under the main Icon module specifically for that object.

what your describing is known as “method chaining”, here’s a link to a very in-depth and well made article on the topic

From Wikipedia, “method chaining eliminates an extra variable for each intermediate step. The developer is saved from the cognitive burden of naming the variable and keeping the variable in mind…
