Cant figure out why method is not working in _generateHours.

 _generateMarkup() {
    console.log(this._weatherIconFormat(this._data.hourly[0].hourCondition));
    `<h1 class="hourly__title title | mb-lg">Hourly</h1>
      <div class="hourly--wrapper">
      ${this._data.hourly.map(this._generateHours).join(" ")}
      </div>`;
  }


  _generateHours(hour) {
    console.log(hour.hourCondition);
    console.log(this._weatherIconFormat(hour.hourCondition));
}
