Why are we passing the "article" object to res.render() in the "/:id" GET route instead of "article.dataValues" ?

Article {
  dataValues: {
    id: 1,
    title: 'Dit is de titel van het eerste nieuwe artikel',
    author: 'Mr Erlando',
    body: 'Dit is dus de body van het eerste nieuwe artikel :)',
    createdAt: 2021-06-25T11:45:10.601Z,
    updatedAt: 2021-06-25T11:45:10.601Z
  },
  _previousDataValues: {
    id: 1,
    title: 'Dit is de titel van het eerste nieuwe artikel',
    author: 'Mr Erlando',
    body: 'Dit is dus de body van het eerste nieuwe artikel :)',
    createdAt: 2021-06-25T11:45:10.601Z,
    updatedAt: 2021-06-25T11:45:10.601Z
  },
