title: retrieve the substring after the first slash
body: <p>I have a String like the following pattern:</p>
  
  <pre><code>string1 / string2 / string3
  </code></pre>
  
  <p>I want to get the following as end string:</p>
  
  <pre><code>string2 / string3
  </code></pre>
  
  <p>I am doing that with the code below. Is there a better way in Javascript to manage that?</p>
  
  <p><strong>code</strong></p>
  
  <pre><code>var key = 'door / chair / screw';
  var keyArray = key.replace('/', ', ');
  var endKey = keyArray[1];
  </code></pre>
