title: Search For Words, Replace With Links
body: <p>I have an  array like this</p>
  
  <pre><code>var words = [
      {
          word: 'Something',
          link: 'http://www.something.com'
      },
      {
          word: 'Something Else',
          link: 'http://www.something.com/else'
      }
  ];
  </code></pre>
  
  <p>I want it to search the page for word and replace it with link. Is there an efficent way of doing this? It seems it may be CPU hungry.</p>
  
  <p>Sorry should have exlained more...</p>
  
  <p>It would search each element with the class .message for instance. Then find all of the words within that.</p>
  
  <p>There would also be a few hundred within this array</p>
