Answer 1

let newArr = 
    {
      "example": "name",
      "word": 12,
      "word": "noone",
      "word": "2014",
      "result": [
        {
          "name": "Ivan",
          "age": "20"
        },
        {
          "name": "OIga",
          "age": "30"
        }
      ]
    };

let newArr2 = newArr.result.map(el => el.age * 2);

let newArr3 = newArr.result.map(el => {
  return {name: el.name, age: el.age * 2};
});

console.log(newArr2);
console.log(newArr3);
