Looks fantastic! Now it simply needs a non-Scratch runtime and a Scratch-like frontend, and we'll finally be able to teach bootstrapping to the 5-10 year old demographic.
I've enjoyed trying to use Deno for a small new service at $WORK. Sadly had to give up and retreat back to Node due to missing support for private NPM repositories and lack of Datadog tracing support.
Their compatibility is getting better and better, so I'm confident Deno will eventually be a clear "better Node".
