title: Sole hash in anchor href?
body: <p>In the project I work on I've recently moved from developing backend (i.e. non-web) servers to web-related things. In the HTML code I've found the following thing all over the place:</p>
  
  <pre><code>&lt;a href='#'&gt;some link&lt;/a&gt;
  </code></pre>
  
  <p>Then some JS is attached to the <code>click</code> event of <code>&lt;a&gt;</code> element.</p>
  
  <p>Does this sole hash has any special meaning? I understand how the <code>href='#some_id'</code> tells the browser to scroll to element with ID = <code>some_id</code>. But <code>href='#'</code> doesn't work that way, right?
  If it's all about creating a clickable piece of text, why not simply use a <code>&lt;span&gt;</code>?</p>
