CODE EXAMPLE FOR JAVASCRIPT

mongoose (populate)

// The 2nd `populate()` call below overwrites the first because they
// both populate 'fans'.
Story.
  find().
  populate({ path: 'fans', select: 'name' }).
  populate({ path: 'fans', select: 'email' });
// The above is equivalent to:
Story.find().populate({ path: 'fans', select: 'email' });
