Functional React Component with an argument in curly braces : <p>I recently came across this piece of code on a website</p>

<pre><code>const List = ({ items }) =&gt; (
  &lt;ul className="list"&gt;
    {items.map(item =&gt; &lt;ListItem item={item} /&gt;)}
  &lt;/ul&gt;
);
</code></pre>

<p>Why have they wrapped the items in curly braces and is it a prop</p>
