What is the purpose of :hooks [leiningen.cljsbuild] in a Leiningen project.clj file?
<p>I have been looking at several project templates for a Clojure/ClojureScript web application. Some have the following line in the Leiningen  project.clj</p>

<pre><code> :hooks [leiningen.cljsbuild]
</code></pre>

<p>while others have not.</p>

<p>What is the purpose of this line? Why would you use it, and why not? Are there advantages, or disadvantages in using this?</p>
