title: Convert neo4j Integer object to JavaScript integer
body: <p>I am storing <code>dateBirth</code> as milliseconds in neo4j.</p>
  
  <p>When using the browser I get this:</p>
  
  <pre><code>match (u:User) return u.dateBirth // Returns -2209078800000 
  </code></pre>
  
  <p>When using the bolt driver (neo4j v3-javascript) I get this:</p>
  
  <pre><code>match (u:User) return toInt(u.dateBirth) as dateBirth
  // Returns: Integer { low: -1465609856, high: -515 }
  </code></pre>
  
  <p>How do I convert this Integer Object to a primitive number in JavaScript?</p>
