This blogger obviously wouldn’t get along with Sean Parent of Adobe. It’s old but I have everyone on my team watch this “no raw loops” presentation: https://youtu.be/W2tWOdzgXHA?si=4LKv1-sau60U63op in which he identifies reusable patterns hiding in code (“That’s a rotate!”) I myself was skeptical at first but have found over the years that breaking functions into pieces is the only way to maintain short functions that can be reasoned about in isolation, and as a side effect, surfaces reusable code. If you can’t write functions that easily fit on a page, I posit you don’t actually know what the function is supposed to be doing, and there’s probably a bug. (If you can’t hold the whole function in your head, how can you be sure there isn’t a bug?)
