This experiment was inspired by an episode of JavaScript Jabber or some similar podcast about web development. The topic of conversation was requestAnimationFrame and so I wanted to see what the fuss was about. I made a simple application that would demonstrate animation — a ball falling. Eventually this evolved into a small physics simulation with the balls bouncing off the “floor” and “walls”. Then in the airport and on the plane from VueConf 2020 (Austin, TX), I added the ability to add new balls.
