title: Is there a & logical operator in Javascript
body: <p>I was wondering if there is a "&amp;" logical operator in Javascript.  I tried running 1 &amp; 0 and 1 &amp;&amp; 0 in Firebug(Firefox) and it returned a 0 for both. </p>
  
  <p>Someone told me that C# accepts both &amp; and double &amp;&amp;, double being more efficient as it will exit the comparison loop as soon as a false is encountered, but I was not able to find any info for Javascript on that.</p>
  
  <p>Any ideas?</p>
