如何在 JavaScript ES6 中使用数组解构并分配给对象属性

Question

This code:

const eat = { when: 'now' }
const fruits = ['apple', 'orange']

eat.fruit = fruits[1] // orange

I can use array destructuring like this:

const [, selectedFruit] = fruits

eat.fruit = selectedFruit

But can I make a one-liner out of it?

Answer 1

Could you use that

[, eat.fruit] = fruits // remove const
console.log(eat)

Answer 2

You can use merging here like:

 let eat = { when: 'now' } const fruits = ['apple', 'orange'] eat = {...eat, fruit: fruits[1]} console.log( eat )
