How can I find the number if I search for “Addendum” using JavaScript?
<p>I have an object like the following:</p>

<pre><code>var RevenueCodes = {
            41020: "Addendum",
            41040: "Cardiology Assessment",
            41060: "Chiropractic Assessment",
            41290: "Neurology File Review - CAT",
            41240: "Neurology Assessment"
            }
</code></pre>

<p>How can I find the number if I search for “Addendum” using JavaScript?</p>
