Sorting algorithm programming exercise (opens in new tab)

A decade ago, I had the pleasure of organise DressCode — an online competition designed spark teenage students’ interest in computer science. Its participants completed a series of programming challenges one of which was to implement a few sorting algorithms. To make it more engaging, I’ve created a JavaScript harness which visualised the algorithm by animating a clowder of longcats. Feedback was positive, I was told, with students appreciating the visual element.
