Concise way to compare against multiple values
<p>Consider the following:</p>

<pre><code>var a = 'jesus';

if(a == 'something' || a == 'nothing' || a=='anything' || a=='everything'){
   alert('Who cares?');
}
</code></pre>

<p>Is there a way to make this shorter?</p>

<p>Is there anything in Javascript like <code>if (a=='bbb'||'ccc')</code>?</p>

<p>In addition, can jQuery help here?</p>
