Change every part's transparency to 1?

Alright, I know exactly how for i, v in pairs work, but, I can't seem to put my finger on how it would change every single part in every single model transparency to 1.

A for i ,v in pairs goes through the loop for as many items that are in the table, so for each item in the workspace, the for loop will run and set it's Transparency to 1

Alright, it's called Recursion, read more about it here: http://wiki.roblox.com/index.php/Recursion

function Bruh(parent)
    for _, child in ipairs(parent:getChildren()) do
        if child:IsA("BasePart") then
            child.Transparency = 1
        elseif child:IsA("Model") then
            Bruh(child) -- recursive step
        end
    end
end
 
Bruh(workspace)
