From the abstract: “Clojure is a modern dynamic language for the JVM, ClojureScript is the same language compiled into JavaScript. This talk will introduce the ClojureScript compiler and explain how it leverages the Clojure language and best-of-breed JavaScript technologies to deliver compact, high-performance web applications. Discover how sharing both data and code between a Clojure back-end and a ClojureScript front-end can make complex web applications simpler, more powerful, and easier to develop.”
