将对象值转换为新数组

Question

这是我的对象：

"names": [{
        "first": "Linda"
    },
    {
        "first": "Maverick"
    },
];

如何将此转换为仅包含first值的数组：

["Linda", "Maverick"]

Answer 1

只需使用Array#map即可：

let data = {"names": [
  {"first": "Linda"},
  {"first": "Maverick"},
]};

let array = data.names.map(name => name.first);

console.log(array)

Answer 3

使用解构和 map：

var names = [
  {
    "first": "Linda"
  },
  {
    "first": "Maverick"
  },
];

var res = names.map(({
  first
}) => first);
console.log(res);
