title: '-%>' (minus sign) at the end of a ERb sequence
body: <p>What's the point of using '-' (minus sign) at the end of a ERb sequence?</p>
  
  <p>Example:</p>
  
  <pre><code>&lt;% 3.times do -%&gt;
    FooBar&lt;br /&gt;
  &lt;% end -%&gt;
  Sometext
  </code></pre>
  
  <p>Regardless of whether I use <strong>'-'</strong> or not, a browser renders the same output.</p>
  
  <p>Thanks, Aplha.</p>
