title: JavaScript Split string by multiple occurrences of letters
body: <p>I am trying to split a string by a single or multiple occurrence of letters.</p>
  
  <p><strong>For example:</strong></p>
  
  <p><code>aaabbcapppp</code>, would yield the array, <code>["aaa", "bb", "c", "a", "pppp"]</code></p>
  
  <p>The most-Inefficient idea I had was to just utilize, <code>newArray = str.split("");</code> and rebuild the array to my needs.  I assume there is a much more efficient solution.</p>
