es6合并对象的方法是什么

ES6合并对象的方法有以下几种:

使用对象展开运算符(…):

const obj1 = {a: 1, b: 2};
const obj2 = {c: 3, d: 4};
const merged = {...obj1, ...obj2};
console.log(merged); // {a: 1, b: 2, c: 3, d: 4}

使用Object.assign()方法:

const obj1 = {a: 1, b: 2};
const obj2 = {c: 3, d: 4};
const merged = Object.assign({}, obj1, obj2);
console.log(merged); // {a: 1, b: 2, c: 3, d: 4}

使用Object.getOwnPropertyDescriptors()方法和Object.defineProperties()方法:

const obj1 = {a: 1, b: 2};
const obj2 = {c: 3, d: 4};
const descriptors = Object.getOwnPropertyDescriptors(obj2);
const merged = Object.defineProperties(obj1, descriptors);
console.log(merged); // {a: 1, b: 2, c: 3, d: 4}

这些方法都可以用来合并多个对象的属性,并创建一个新的对象。
