+<p>In our <a href="https://github.com/mdn/fetch-examples/tree/master/fetch-json">fetch json example</a> (run <a href="http://mdn.github.io/fetch-examples/fetch-json/">fetch json live</a>), we create a new request using the {{domxref("Request.Request")}} constructor, then use it to fetch a <code>.json</code> file. When the fetch is successful, we read and parse the data using <code>json()</code>, then read values out of the resulting objects as you'd expect and insert them into list items to display our product data.</p>

+<pre class="brush: js">var myList = document.querySelector('ul');

+var myRequest = new Request('products.json');
+
+fetch(myRequest)
