title: lodash .get replace empty value
body: <p>so i am using lodash <code>.get</code> to copy some array from my database to create a excel documents by using this</p>
  
  <pre><code>object[key.key] = _.get(item, key.key, '-');
  </code></pre>
  
  <p>where <code>key</code> is set of array and <code>key.key</code> is set of array column name or field name. it works fine replacing undefined value from database to <code>-</code> but there is also some fields that just have an empty value and i want to catch those fields and also changing it into <code>-</code></p>
  
  <p>how to do that?</p>
