I made a short screencast about the Advent of Code (day 1), and how to solve it entirely in IEx.

2019 is my first year checking it out, and it’s interesting to see everyone else’s solutions on Github. One of my favorites was Sasa Juric’s solution, which used &Stream.iterate/2 to do the recursion necessary in the 2nd part of the problem.
