在es6中是否可以将对象分解为新对象? [英] Is there a way to destructure an object into a new object in es6?

问题描述

例如，我有这个对象:

const payload = {
    apple: 1,
    dog: 2,
    cat: 3
}

，我想将其分解为仅包含apple和dog的新对象:

and I want to destructure it into a new object that only contains apple and dog:

const newPayload = {
    apple:1,
    dog: 2
}

类似:

const {{apple, dog} : newPayload} = payload

显然以上说法是错误的，但想知道是否有一种方法可以做到这一点.

Obviously the above is wrong, but wondering if there is a way to do something like this.

谢谢！

推荐答案

您可以使用delete:

const newPayload = { ...payload };

delete newPayload.cat

或者:

const { cat, ...newPayload } = payload;

Lodash也有omit():

const newPayload = _.omit(payload, ['cat']);
