与对象解构相反

Question

给出以下示例.是否有现场指定的简写

let myObj = {someField: 'someValue'}
let foo = 'value'

myObj.foo = foo // I would like to do the opposite of object destructuring: const {foo} = myObj. I don't want to repeat foo twice.

Answer 1

你可以使用Object.assign一个短手属性.

const myObj = {}
const foo = 'value'

Object.assign(myObj, { foo });

console.log(myObj);
