如何在对象属性上使用数组解构？

Question

const arr = [1,2];

const respond = {};

respond.obj = arr[0];

The above code giving me eslint error prefer-destructuring . I understand what's it trying to tell but I'm wondering about my above case is possible?

Below is what I thought it might be working but apparently no

const [respond.a,b] = arr;

Is there any similar approach that gives me something as above?

Answer 1

You could try this

 const arr = [1,2]; const respond = {}; [respond.obj] = arr; console.log(respond); 

Or you can disable the rule for this line:

respond.obj = arr[0]; // eslint-disable-line prefer-destructuring

Answer 2

It tells you that you have to destructure the array in the first line.

const [firstNumber, secondNumber] = [1,2];

const respond = {};

respond.obj = firstNumber;

console.log(respond);
