title: String manipulation with Javascript (NodeJS)
body: <p>I'm trying to remove the first 13 characters of a string with this code:</p>
  
  <pre><code>requestToken = requestToken.substring(13);
  </code></pre>
  
  <p>However, I'm getting "<code>has no method substring</code>" error with NodeJS, the code above that mostly recommended in the Javascript forums does not work with NodeJS? </p>
