Uncaught ReferenceError: hello is not defined
<p>Any idea why I have the error <strong>Uncaught ReferenceError: hello is not defined</strong> ?</p>

<pre><code>function hello() {
    console.log('hello ()');
    setTimeout("hello ()", 1000);
}
setTimeout("hello()", 1000);​
</code></pre>

<p>Here is a jsfiddle : <strong><a href="http://jsfiddle.net/s9vLk/" rel="nofollow">http://jsfiddle.net/s9vLk/</a></strong></p>
