title: Javascript - match Regex for this date represenation
body: <p>How can I write a proper regex for:   </p>
  
  <pre><code>/Date(1518238800000)/ - matches
  
  jdsjdsj - no match
  
  2017/03/12 - no match
  
  12 - no match
  
  Date() - no match
  
  /Date(1218238800000)/ - matches
  </code></pre>
  
  <p>What I have so far is:</p>
  
  <pre><code>var res = str.match(/Date(\d*)/g);
  </code></pre>
  
  <p>How can I amend the regex to work?</p>
