Since the start of the course I had been cringing at each occasion in which we used direct input references, but following as I had seen it would be refactored later. I still thought it was strange to not do it “proper” from the start.
Now I can say: THANKS. This lesson taught me how to go about refactoring something like that in an easy and tidy manner, whereas before I would have just panicked and considered a similar refactoring as something huge, complicated, and nightmarish, with a huge potential for mass failure.
This is going to be a huge skill, probably more important than anything else the course taught so far (and man, did it teach me a LOT. It’s mindblowing.)
