you can make a generic function which take array of objects and return array with modified-props objects using map() and Object.assign().

const users = [
    { name: 'Jhon', logged: 'Tue Feb 04 2020 14:16:10 GMT+0200 (Eastern European Standard Time)'  },
    { name: 'Doe', logged: 'Tue Feb 04 2020 14:20:10 GMT+0200 (Eastern European Standard Time)'  }
];


const handleDates = (list, prop) => {
    return list.map(item => {
      const obj = Object.assign({}, item);
      obj[prop] = new Date(obj[prop]).toLocaleDateString();
      return obj;
    });
}

console.log(users)
console.log(handleDates(users, 'logged'))
