I maintain a github repo where I implement the same feature identical rudimentary news feed microservice in different programming languages and frameworks. Here is the social broadcast function in clojure. https://github.com/gengstrand/clojure-news-feed/blob/master/server/feed13/src/feed/services/outbound.clj#L11-L21 https://github.com/gengstrand/clojure-news-feed/blob/master/... and in python https://github.com/gengstrand/clojure-news-feed/blob/master/server/feed5/swagger_server/services/outbound_service.py#L26-L43 https://github.com/gengstrand/clojure-news-feed/blob/master/... and in node.js javascript https://github.com/gengstrand/clojure-news-feed/blob/master/server/feed4/services/OutboundService.js#L5-L49 https://github.com/gengstrand/clojure-news-feed/blob/master/... That last one is pretty old and predates async and await.
