title: Regular Expression to get the last word from TitleCase, camelCase
body: <p>I'm trying to split a TitleCase (or camelCase) string into precisely two parts using javascript. I know I can split it into multiple parts by using the lookahead:</p>
  
  <pre><code>"StringToSplit".split(/(?=[A-Z])/);
  </code></pre>
  
  <p>And it will make an array <code>['String', 'To', 'Split']</code></p>
  
  <p>But what I need is to break it into precisely TWO parts, to produce an array like this:</p>
  
  <pre><code>['StringTo', 'Split']
  </code></pre>
  
  <p>Where the second element is always the last word in the TitleCase, and the first element is everything else that precedes it.</p>
