a list of natural numbers for us.
</p>
<p>For our first version, we will use only the <code class="mendoza-code">while</code> form to iterate,
similar to how one might sum natural numbers in a language such as C.
</p>
<pre class="mendoza-codeblock"><code data-language="janet">(<span class="mdzsyn-coresym">var</span> <span class="mdzsyn-coresym">sum</span> <span class="mdzsyn-number">0</span>)
(<span class="mdzsyn-coresym">var</span> <span class="mdzsyn-symbol">i</span> <span class="mdzsyn-number">0</span>)
