title: Why Number#toLocaleString() doesn't work as expected in both webkit console and node console?
body: <pre><code>var a = 1234567;
  
  console.log(a.toLocaleString())
  
  #=&gt; '1234567'
  </code></pre>
  
  <p>Why there's no difference between toLocaleString() and toString in this test?</p>
