title: Difference between [] and {{}} for binding state to property?
body: <p>Here is an template example:</p>
  
  <pre><code>&lt;span count="{{currentCount}}"&gt;&lt;/span&gt;
  &lt;span [count]="currentCount"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>Here both of them does the same thing. Which one is preferred and why?</p>
