Question

给出以下示例。是否有字段对齐的简写

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

您可以将Object.assign与short hand property一起使用。

const myObj = {}
const foo = 'value'

Object.assign(myObj, { foo });

console.log(myObj);

Answer 2

如果你转换你的陈述，你可以这样做：

const foo = 'value';
const myObject = { foo };

或者如果您从const更改为var，那么您可以为myObj分配新对象：

var myObj = {};
const foo = 'value';
myObj = { foo }

与对象解构相反
