Javascript define variable notation question
<p>Saw some JS notation today that I've never seen before, bear with me if it is something common that everyone knows.</p>

<pre><code>var cookiepath = cookiepath || '';
</code></pre>

<p>Now, is this just saying, if a variable named cookiepath already exists, set it to cookiepath or if it doesn't, set it to ''?</p>
