Sorting the cloumns in Datatable while working with Lightning Component

I am giving the simple idea to implement the sorting functionality for the datatable.

Create the following Apex Class -
Create the following Lightning Component -
Create the following Lightning Controller Js - Create the following Lightning Helper Js - Create the following Lightning App in which you can see the preview for the above created component - I still didn't work on showing the up and down arrows which I might work in future. (Please comment if you want that functionality to add, with some response it will be encouraging me to work on that part as soon as possible.)
