javascript - 优先合并两个 JavaScript 对象

Question

这个问题已经有答案了:

How can I merge properties of two JavaScript objects dynamically? (69 个回答)

已关闭 7 年前。

我有两个 JavaScript 对象，例如

let master = {A:0, B:2};
let slave = {B:1, C:1};

我需要:

result == {A:0, B:2, C:1};

JS有一个简单的命令可以这样合并吗？

使用Object.assign

The Object.assign() method is used to copy the values of all enumerable own properties from one or more source objects to a target object. It will return the target object.

let master = {A:0, B:2};
let slave = {B:1, C:1};

console.log(Object.assign(slave, master));
