Function in a custom data type

Help and Feedback Scripting Support
#1

i know you can create a custom datatype like that:

type NameDoNotMatter = {
-- anything here
}

so for example if we do:

type BlaBlaBla = {
D: number,
G: string
}

then if we do:

local d: BlaBlaBla

d.D -- Number
d.G -- String

but can you make a function like?

CustomDataType:FunctionName
or
anyString:Format

#2

Yeah you can give a custom datatype functions (because they are basically tables) but not the default ones.

#3

Also custom datatypes by roblox are created by constructors of a class thus why they can have functions that are inherited.

#4

i have an idea!

() → () means function.
so i can do this but then in the constructor function, i define the efuncction"

#5

What do you mean? All you need to do is define the functions of the class then let the datatype inherit it.

also if you want to control function arguments types you can do this:

--type module
export type myFunction<Type> = (argument: Type) -> (number)
