Clojure Tutorial - Make a function that can only run once!

Hey guys! I’m super amped to have made a video with Peter, the guy who introduced me to Clojure :) He is also the author of a number of Clojure libraries!

This video covers solving a problem using Clojure. The problem here being the need for a function that can only run once.

This video covers problem solving, creating good docstrings, using atoms and checking thread safety.

This video was super exciting to make and I think it turned out really well. The follow up to this video will be launched next week, as the total film time was really long so I think it was better to split the videos up.
