MongoDB's <code>find()</code> method returns a cursor object which can be iterated using <code>while</code>, <code>hasNext()</code> and <code>next</code>, or by using <code>forEach()</code>.<div style="min-height:25em"></div>
<div class="q nonum" data-lang="mongo">
<p class="strong">Iterating countries in South America stored in the 'world' collection.</p>
<pre class="def"><nowiki>
let cursor = db.world.find({continent: "South America"});
while (cursor.hasNext()) {
   printjson(cursor.next());
}</nowiki></pre>
</div>

<div class="q nonum" data-lang="mongo">
<pre class="def"><nowiki>
let cursor = db.world.find({continent: "South America"});
cursor.forEach(printjson);</nowiki></pre>
</div>

Cursors can also be converted to other JavaScript collection types, such as arrays.<br/>
In the following example an array is used to find the '''n'''th record in a result as an alternative to <code>.find().skip(n).limit(1)</code>
<div class="q nonum" data-lang="mongo">
<p class="strong">Find the 3rd result of the previous example.</p>
<pre class="def"><nowiki>
db.world.find({continent:"South America"}).toArray()[3];</nowiki></pre>
</div>
