Couldn't agree more with the necessity for fast feedback loops. I've experienced the opposite, and it's not fun.

I worked with Clojure/ClojureScript (mostly ClojureScript) for a couple of years many years ago. It was the first time I'd worked professionally with a functional language, so I made a game of minesweeper in my free time to help get to grips with it: https://github.com/robjinman/cljsmines

Back then, I fully bought into the idea that functional language like Clojure were the future, especially on the web. The way application state is managed is perhaps the key virtue of functional programming - if you get it right, you can design your program to consist mostly of completely pure functions. I remember how enlightening that was once I understood it.
