I guess though, the people in the Ruby / Django community are actually building projects and the node community are padding their resume with new npm packages.
I hope deno or dart can make the JS world better, but I suspect they will both end up just making it more fragmented. One thing I really like on flutter / dart is they do try to rate / otherwise rank / categorize support of their packages aside from stars https://pub.dev/packages?sort=popularity / downloads which are easy to manipulate. IMO deno should do this as well or let someone willing to takeover as the primary package manager https://deno.land/x/lodash@4.17.19
