title: Why set 'numberposts' to -1?
body: <p>When creating a custom wordpress query, why would someone set their 'numberposts' to -1? What is the outcome? I've googled a bunch and can't seem to find this (probably) very simple answer! </p>
  
  <pre><code>ex: $args = array( 'numberposts' =&gt; -1);
  </code></pre>
