JS<p><pre><code>  var result = exclaim(capitalize(doubleSay(&quot;hello&quot;)));
</code></pre>
ES7 Proposal: The Pipeline Operator<p><pre><code>  var result = &quot;hello&quot;
    |&gt; doubleSay
    |&gt; capitalize
    |&gt; exclaim;
</code></pre>
CoffeeScript<p><pre><code>  result = exclaim capitalize doubleSay &#x27;hello&#x27;
</code></pre>
I&#x27;ll take CoffeeScript.
