In June 2018, Ryan Dahl took the stage at JSConf EU in Berlin, the largest nonprofit JavaScript conference in the world. Despite it being a high-profile event (and the fact that the majority of the 1,500 conference attendees had filed into this particular warehouse just to see him), Dahl wore a loose-fitting black T-shirt and jeans and kept things casual. “So, I kinda wanted to give a different talk about some other stuff, but that wasn’t ready, so this is kind of a make-up talk,” he began. Dahl seemed nervous. Given what he was about to do, nerves made sense.
