Shriyans Bhatnagar uses Rx.js on a daily basis in work, mostly combining it with React and redux. Being a full stack developer, I often find myself using Rx on Node too. Playing around with a few Reactive libraries—RxJs, most.js, and, bacon.js—and Reactive frameworks such as cycle.js, I absolutely love writing functional Reactive code. I am an avid fan of pure functional programming. I have played around with Haskell, elm, and erlang quite a lot and have some experience writing clojureScript. These days I really dig ReasonML (a new interface to OCaml by Facebook).
