David Nolen is out evangelizing ClojureScript. Not ClojureScript itself directly. But the philsophy of ClojureScript–how immutable data structures can be fast (sometimes faster than their mutable counterparts), how immutability simplifies systems, how interactivity can be functional. It may be preaching to the choir if you subscribe to this newsletter. But this is important stuff. It’s yet another example of how Clojure is affecting the rest of the industry and is on the cutting edge of software engineering.
