Expected ')' (to close '(' at line 1), got <eof>? [closed]

Here are my scripts:

script.Parent.MouseButton1Click:Connect(function()
    local folder = game.Workspace:FindFirstChild("Folder")
    folder:Destroy()
end)

2nd:

script.Parent.MouseButton1Click:Connect(function()
    local folder = Instance.new("Folder")
    folder.parent = game.Workspace
    while true do
        local part = Instance.new("Part")
        part.parent = folder
        part.Anchored = false
        wait()          
    end
end
