将对象的子集直接解构为新对象[重复]

有没有一条语句可以做到这一点，我正在空白？

// this.state is a basic object with many keys
var {toDate, fromDate, location, flavor} = this.state
var goodKeys = {toDate, fromDate, location, flavor}
// goodKeys is an object that contains a subset of this.state's keys

我能想到的唯一办法是：

var {keyIDontWant, otherUnwanted, ...goodKeys} = this.state

但这似乎会让阅读代码的人感到困惑，并且需要花费更多的精力来弄清楚如何编写。

_.pick https://www.npmjs.com/package/lodash.pick仍然是在 ES6 中拥有用例的 Underscore/Lodash 功能之一。

ES6 单行代码可能是 IIFE，并且会导致属性列表枚举两次：

let goodKeys = (
  ({toDate, fromDate, location, flavor}) => ({toDate, fromDate, location, flavor})
)(this.state);

ES.next 对应的单行_.pick可能涉及Object.entries https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries:

Object.entries(o)
.filter(([key]) => ['toDate', 'fromDate', 'location', 'flavor'].includes(key))
.reduce((obj, [key, val]) => Object.assign(obj, { [key]: val }), {});
