export function getPerson() {

    age,
    fistName: 'Benny',
    lastName: 'Neugebauer',
  };
}

Fixed Code ✔️

If you want to use the shorthand property name syntax to access the age property, you have to make sure that this variable is defined in the first place:

1

export function getPerson() {
  const age = 34;
  return {
    age,
    fistName: 'Benny',
    lastName: 'Neugebauer',
  };
}

Alternatively, you can avoid using the shorthand property name syntax:

export function getPerson() {
  return {
    age: 34,
    fistName: 'Benny',
    lastName: 'Neugebauer',
  };
}
