In Javascript, given value, find name from Object literal
<p>I'm new JavaScript and trying to find out an easier way to find name given a value from object literal.</p>

<p>e.g.</p>

<pre><code>var cars ={ Toyata: ['Camry','Prius','Highlander'],
            Honda:  ['Accord', 'Civic', 'Pilot'],
            Nissan: ['Altima', 'Sentra', 'Quest']};
</code></pre>

<p>Given 'Accord', I want to get Honda from the object Cars.</p>
