Learn how to build complete client-side applications with ClojureScript, the Clojure language variant that compiles to optimized JavaScript. This hands-on introduction shows you how ClojureScript not only has similarities to JavaScriptwithout the flawsbut also supports the full semantics of its parent language. Youll delve into ClojureScripts immutable data structures, lazy sequences, first-class functions, macros, and support for JavaScript libraries.No previous experience with Clojure or ClojureScript is necessary. If youre familiar with JavaScript, HTML, CSS, and the DOM, youll quickly discover that ClojureScript has the same reach as JavaScript, but with more power.Start writing ClojureScript code with the Leiningen build systemLearn how the ClojureScript compiler works to produce optimized JavaScriptUse JavaScript functions and libraries directly from ClojureScript codeExplore functions in Clojures sequence library such as map, reduce, and filterUse macros to define new control structures or embed domain-specific languagesCompile manually or script your own workflow with ClojureScripts compiler toolsIntegrate ClojureScript with Clojure on the JVM to build powerful client-server applications.
