title: Finding first alphabetical letter in a string - Javascript
body: <p>I've done some research and can't seem to find a way to do this. I even tried using a for loop to loop through the string and tried using the functions <code>isLetter()</code> and <code>charAt(</code>).
  I have a string which is a street address for example:</p>
  
  <pre><code>var streetAddr = "45 Church St";
  </code></pre>
  
  <p>I need a way to loop through the string and find the first alphabetical letter in that string. I need to use that character somewhere else after this. For the above example I would need the function to return a value of <strong>C</strong>. What would be a nice way to do this?</p>
