nes it with the remaining elements in iteration order,
as if by:</p>
<pre class="language-dart"><code>E value = iterable.first;
iterable.skip(1).forEach((element) {
  value = combine(value, element);
});
return value;
</code></pre>
<p>Example of calculating the sum of an iterable:</p>
<pre class="language-dart"><code>iterable.reduce((value, element) =&gt; value + element);
</code></pre>
