If you can see this, React is not working right. This is probably because you&apos;re viewing
this on your file system instead of a web server. Try running
<pre>
python -m SimpleHTTPServer
</pre>
and going to <a href="http://localhost:8000/">http://localhost:8000/</a>.
</p>
</div>
<h4>Example Details</h4>
<p>This is written with JSX in a separate file and transformed in the browser.</p>
