title: Angular2 or TypeScript Left padding a String with Zeros
body: <p>I have a number let say 9. But I need it as String "09".</p>
  
  <p>I know i can write my own logic. But I am looking for a implicit util function which can pad it.</p>
  
  <p>I am using angular2 with TypeScript. Looking for something like <a href="https://stackoverflow.com/questions/4469717/left-padding-a-string-with-zeros">this</a>.</p>
  
  <p>Just Similar like java</p>
  
  <pre><code>String.format("%010d", Integer.parseInt(mystring));
  </code></pre>
