  How to add fetch's answer to the constructor. With the possibility of withdrawal?
  I teach classes.
  Or how to output fetch c class correctly.
  
  

  class Board {
    constructor() {
      //this.data = result getReferral
    }
  
    getReferral(url) {
      return fetch(url)
        .then(response => response.json())
        .then(data => console.data(data))
    }
  }
  
  const ruler = new Board();
  const referral = ruler.getReferral();
  
  console.log(ruler.data);
