title: Dot operator in javascript
body: <p>I think that the dot operator can be apply to object only for access to his properties. I.e. for instance </p>
  
  <pre><code>var o={prop:'property'};
  alert(o.prop);//property
  </code></pre>
  
  <p>When JS executing <code>alert(o.prop);</code> first object which contains by reference <code>o</code> will found further will be found property wich contains by reference <code>o.prop</code>.</p>
  
  <p>Let's write</p>
  
  <pre><code>simple='hello';
  alert(simple.length);//5
  </code></pre>
  
  <p>I dont understand this. I'm excepted that in console will kind of error, because simple is no object.</p>
