在ES6中有没有一种方法可以将一个对象分解成一个新的对象？

Question

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

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

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

Answer 1

您可以使用delete:

const newPayload = { ...payload };

delete newPayload.cat

或：

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

Lodash还有Omit():

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