body: <p>How do I obtain AsCII Code of a lowercase of an Uppercase alphabet in Javascript</p>
  
  <p>I understand I can  use <code>toLowerCase</code> or <code>toUpperCase</code> to do this but I don't wish to use them in this scenario:</p>
  
  <p>So assuming I have this:</p>
  
  <pre><code>var string = "ABC".charCodeAt(0) //which returns 65 for character 'A'
  </code></pre>
  
  <p>How do do I get the lower case of 'A' without using <code>toLowerCase</code></p>
  
  <p><strong>Reason:</strong> I am trying to build a custommized <code>toLowerCase</code> and <code>toUpperCase</code> based on what we are working on</p>
  
  <p>Please pardon me if this is not possible. I just need a solution</p>
