I'm not sure if I would use this myself, but it's interesting how Ryan Dahl attempts to correct what he perceives were mistakes when he first created Node.js [1]. It's cool that Deno has backpressure built into the runtime -- which adds a mark in favor of promises in the debate between events and promises.

I can't think of too many selling points for this though. I already know Node and if I'm going to invest time to learn another runtime, why not spend that time learning Go or Crystal or something besides something that will likely split the Node community?
