Okay I'm trying to understand how to do programming without variables.
I've managed a simple tic-tac-toe game but it depended on a tail recursive state and as far as I can tell would only work in a single thread. Example can be seen at https://codereview.stackexchange.com/questions/187339/scala...
it has been suggested to me that this may be a better fit for softwareengineering.stackexchange.com I tried asking in their chat room but no answer. — Wes30 secs ago
