Is this article (and the one it refers to) taking a good or bad approach to program structure?
http://7sharpnine.com/2016/10/03/building-an-spa-with-elm/ I copied the structure as a way of seeing how a program might perhaps be broken down, but it feels like a very component based approach, given each level has its own update function. I learnt a fair bit about mapping between message types, so it was useful. I've broken my app down into pages using this structure, and so each page has a view, model, etc. Then the top level model has a model record for each page. This seems to work as it means the page doesn't need to know how it's being used at the level above. But the general conversations I see suggests this is not the right way to go and to break things down more into modules of related code. So I guess back to the original question, is this structure a good way to work?
