title: Empty values in if clauses
body: <p>Here's a sample code:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;button onclick="myFunction();"&gt;Click!&lt;/button&gt;
  &lt;script type="text/javascript"&gt;
  function myFunction() {
  var text = "";
  if (text)
    {
    alert(text);
    }
  else
    {
    alert("There's no text!");
    }
  }
  &lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I wonder is there's a difference between <em>if (text)</em> and <em>if (text != "")</em>?</p>
  
  <p>Thanks in advance!</p>
  
  <p>Mike</p>
