Dart looks very elegant. You didn't include "group all the articles based on the author". Would that be equally clean in Dart? Here's the Clojure version: ;; given articles = [{:title "t1" :author "a1" :tags #{:t1 :t2}} .. etc. ] ;; These 4 Clojure one-liners replace all the J8 code examples in the article.
