  <p>In this case I'm trying to pass a value to variable "maxage":</p>
  
  <pre><code>var dateFilter = function(value,maxage) { // Age in miliseconds
      if(Date.now() - value &lt; maxage) {
          return value;
          } else {
          return false;

      }
  
      dates.filter(dateFilter,500);
  </code></pre>
