JavaScript: what's the difference between a function name & function reference?
<p>I'm reading the Google Maps API and it states that the:</p>

<pre><code>"callback: The function to call once the script has loaded. If using the Auto-loading feature, this must specify a function name, not a function reference.
</code></pre>

<p>What's the difference been a JavaScript function name vs a function reference?</p>
