What does "in pairs" do?

i = index v = the current index value this loops through the table for its values or parents for its children. this loop basically scans through everything inside an object or whatever and returns a value. Example:

for i, v in pairs(Workspace.Model:GetChildren()) do
if	v.Name == "Wall" then
v.Transparency = 0.5
end
end

this would loop through a model in the workspace named model and look for an object with the name wall, if it find one, it would change the objects transparency to 0.5. This is usefully for changing multiple items in your place or getting special things from your player.
