❗️Что будет на выходе:

const obj = {
  name: 'Sarah',
  getName() { return this.name; },
  getNameArrow: () => this.name
};

const { getName, getNameArrow } = obj;
const boundGetName = obj.getName.bind(obj);

console.log(getName());
console.log(getNameArrow());
console.log(boundGetName());
console.log(obj.getName());
console.log(obj.getNameArrow());

Ответ: undefined undefined Sarah Sarah undefined
