title: access of an array inside another array in javascript
body: <p>i have two arrays defined like these</p>
  
  <pre><code>var theory= new Array();
  var first;
  var second;
  
  function arrTheory () {
      this.first= first;
      this.second= second;
  }
  
  var subject= new Array();
  ...
  function arrSubject () {
      ...
      this.theory= theory;
      ...
  }
  </code></pre>
  
  <p>how can i access to the elements in the theory array inside the bigger one?
  I've tried</p>
  
  <pre><code>subject[0].theory.first;
  </code></pre>
  
  <p>but it doesn't work while</p>
  
  <pre><code>subject[0].name;
  </code></pre>
  
  <p>which is another field of the big array works fine. what i've missed?</p>
