What does ["String"] mean in a module script?

Help and Feedback Scripting Support

I’m looking at the source code of HD’s admin in order to get the picture of how an admin script is made and as I myself don’t know the first thing about copyright law I’ll just post an example I made:

Module Script

["String"] = {
Function = function(speaker, args)
local val1 = tick()
local returnValue = getPing 
end
}

This is hopefully going to help get my question across, what does the [“string”] do?

[“String”] is the parent of Function. It’s essentially the same thing as:

String = {}

String.Function = -- function

Unrelated but been wondering this for a while, how do I get the ‘programmer’ tag next to my username?

It’s inside a table. It’s just defining a key in a table

local tab = {
    String = function()
        print("something")
    end
}

-- is the same as

local tab = {
    ["String"] = function()
        print("something")
    end
}

-- is the same as

local tab = {}
tab.String = function()
    print("something")
end
