Last year while doing advent of code I came across the APL programming language. I had always been interested in exploring array programming, but the highly imperative nature of tools like NumPy, R, Julia and Matlab turned me off. Luckily APL has the best of both worlds as a functional array programming language with first class support both for functions and multi-dimensional arrays. More recently I've been playing around with BQN, a modern variant of APL, which is what I'll be exploring today.
