对象解构的正确方法

Question

我有一个场景，我从承诺中收到一个对象，需要将这个对象的一些键添加到另一个对象。例如：

// Received from promise
object_1 = {
    name: 'SH'
};

// Want to add object_1.name to object_2 
object_2 = {
    id: 1234
};

通常我可以像下面那样做，但我想用对象解构来做

object_2.name = object_1.name;

拥有：

object_2 = {
    id: 1234,
    name: 'SH'
};

Answer 1

您可以使用 destructuring assignment to a target object/property with a object property assignment pattern [YDKJS: ES6 & Beyond].

var object_1 = { name: 'SH' },
    object_2 = { id: 1234 };

({ name: object_2.name } = object_1);

console.log(object_2);

Answer 2

您可以像这样使用对象析构来实现预期的输出：

// Received from promise
object_1 = {
    name: 'SH'
};

// Want to add object_1.name to object_2 
object_2 = {
    id: 1234
};

object_2 = {
  ...object_2,
  ...object_1
}
