title: Confusing with Regular Expressions repeaing parts
body: <p>I am really confused with Regular Expressions repeating parts with curly braces. Consider the following example: </p>
  
  <pre><code>var dateTime = /\d{1,2}\/\d{1,2}\/\d{4} \d{1,2}:\d{2}/;
  console.log(dateTime.test("30/1/2003 8:45"));
  // true
  </code></pre>
  
  <p>Now if I change 30 to 300000 and 45 to 455555, I'll get true again! Other parts between outer numbers are ok and the result is as expected.</p>
  
  <p>Can somebody help me find the problem?</p>
  
  <p>Thanks.</p>
