I love anything that hooks me subject-wise to keep learning J. I always get charged to ply my J skills and learn from others. I tried to run a batch of simulations for x amount of days with the default number of people in the code as follows, but I am sure the infect function is not randomizing on each simulation run, and I am misusing ^:<p><pre><code> avg^:5 (# I. infect^:10 starting_pop = 0)</code></pre>
