对象结构的Javascript转换数组

Question

我正在尝试将对象结构数组从如下所示进行转换:

[
  {
    id: 1,
    val: "bool",
    name: "somename",
    entities: [
      {
        id: 1,
        name: "varchar",
        type: "string"
      }
    ]
  },
  {
    id: 2,
    val: "bool",
    name: "somename",
    entities: [
      {
        id: 1,
        name: "varchar",
        type: "string"
      }
    ]
  }
]

进入这个:

[
  {
    id: 1,
    val: "bool",
    name: "somename",
    entitiesName: "varchar",
    entitiesType: "string"
  },
  {
    id: 2,
    val: "bool",
    name: "somename",
    entitiesName: "varchar",
    entitiesType: "string"
  }
]

所以或多或少我想从 entities 中获取两个值，并将它们变成根对象中的键/值。

我尝试过使用 Object.entries(data).map() 但我卡住了

您可以使用销毁来收集所有需要的属性并构建一个新对象。

var array = [{ id: 1, val: "bool", name: "somename", entities: [{ id: 1, name: "varchar", type: "string" }] }, { id: 2, val: "bool", name: "somename", entities: [{ id: 1, name: "varchar", type: "string" }] }],
    result = array.map(
        ({ id, val, name, entities: [{ name: entitiesName, type: entitiesType }] }) =>
        ({ id, val, name, entitiesName, entitiesType })
    );

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
