title: clojurescript advanced compilation - size
body: <p>I am new to clojurescript.</p>
  
  <p>Is it normal to have a javascript file of "77 KB" after advanced compilation?</p>
  
  <p>I have one clojurescript file:</p>
  
  <p>I am using leinigen: lein cljsbuild once</p>
  
  <pre><code>(ns my-staff.core)
   (defn ^:export main []
     (.write js/document "&lt;p&gt;Hello from my_staff.core.main()&lt;/p&gt;")) 
  
  (defproject my-staff "0.1.0-SNAPSHOT"
    :dependencies [[org.clojure/clojure "1.4.0"]
                   [org.clojure/clojurescript "0.0-1586"]]
    :source-paths ["src-clj"]; source path for clojure
    :plugins [[lein-cljsbuild "0.3.0"]]
    :cljsbuild {
       :builds [{
            :source-paths ["src-cljs"]
            :compiler {
            :output-to "public/javascripts/main.js"
            :optimizations :advanced
            :pretty-print false}}]})
