Clojure tutorial - use an atom to make a run once function wrapper!
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 https://github.com/ptaoussanis
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.
