title: Array.length in Javascript is not working
body: <p>I tried to get length from array but it worked abnormally. Here is my object,</p>
  
  <pre><code>var user = {
    "username":"testuser update",
    "email":"user001@mail.co.th",
    "name":"user001",
    "ownAccount":"[
      {"id":2,"name":"Demo Account2"},
      {"id":1,"name":"Demo Account"}
    ]"
  }
  </code></pre>
  
  <p>I want to get length of ownAccount, I tested by logging it,</p>
  
  <pre><code>console.log(user.ownAccount.length);
  </code></pre>
  
  <p>It showed <strong>64</strong> !!!, it didn't show <strong>2</strong>. 
  I didn't understand what I did wrong.</p>
  
  <p>Thanks for help.</p>
