Does it? Last I tried, several years ago, coverage of the Node APIs was not good. I wanted to send data over UDP and a lot of Node basics there were missing.
They're still missing niche things and they tend to target the things that most devs (and their dependencies) are actually using.
But I can see they have it in their compat stuff now and it looks like it's working in the repl locally: https://docs.deno.com/api/node/dgram/
