+<h3>Defining composable functions</h3>
+
+<p>Function composition is a mechanism for combining functions, in which the
+output of each function is passed into the next one, and the output of the last
+function is the final result.  In this example we use <code>reduceRight()</code>
+to implement function composition.</p>
