javascript - 从对象获取属性以转换为简单数组 - javascript

Question

我有这个数组：

[
  {
    "id": "5e235b42a21b160a40c4a82f",
    "title": "category one"
  },
  {
    "id": "5e235b3ea21b160a40c4a82e",
    "title": "category two"
  }
]

我想将其转换为以下数组：

[
  "5e235b42a21b160a40c4a82f",
  "5e235b3ea21b160a40c4a82e"
]

有人有一个简单的建议吗？

The best way to do this is by iterating over the Object values and taking each id value.

The simplest way of doing this is by using .map() like so:

const newArray = myArray.map(item => item.id);

This should take each item and form the id property into an array.
