javascript - 如何使用扩展运算符更改对象的嵌套属性？

Question

这是我的情况的一个干净版本:

const person1 = {
    name: "Person1 Name",
    hairColor: "Brown",

    backpack: {
        color: "Army-Green",
        content: [
            "item1",
            "item2",
            "..."
        ]
    }
}

我试图只更改 背包颜色

我已经在下面尝试过这段代码，但没有成功:

person = {...person1, backpack.color: "New backpack color"}};

person = {...person1, backpack: {...backpack, color: "New backpack color"}};

person = {...person1, backpack: {color: "New backpack color"}};

person = {...person1, backpack = {...backpack, color: "New backpack color"}};

Answer 1

const person2 = {...person1, backpack: {...person1.backpack, color: 'Red' }}
