I had hoped they would continue discussion project organization to how this relates to Angular modules, but they did not. I assume Angular modules apply the similar concept to a larger scale, each module a collection of components, but I don’t know for sure and haven’t seen how it would be useful.
The componentization tutorial has one aspect unique among all of these tutorial pages: After following through all the steps on the page, the end-user visible web app looks exactly the same. All our effort was spent organizing code behind the scenes without disturbing the user facing visible appearance. I thought it was neat but some may find it pointless. Either way, this would be the last time we “do nothing” in this tutorial.
