title: Getting the biggest(or highest) letter
body: <p>If we want to get the max or min value we use <code>Math.max</code> or <code>Math.min</code> . I wonder if there is a way to get the highest letter. </p>
  
  <p>For example;</p>
  
  <pre><code>var i = 'A';
  var ii = 'B';
  var iii = 'C';
  
  result = getthemax(i , ii, iii);   
  // so result equels to 'C'
  </code></pre>
  
  <p>I searched a lot but can't find anything like this. Is there any way to do that? </p>
