Object destructuring solution for long arrays?

Question

Looking at this code:

let lecture = {
    id: 2,
    title: \"MyTitle\",
    topics: [
    {
        title: \"John\",
        age: 1
    },
    {
        tit         


        

Answer 1

Probably too late to reply this,

const index = 65
const {title: lectureTitle, topics: {[index]: {age: thirdAge}}} = lecture

because in real life we normally would be using dynamic indices for arrays to destructure, square brackets instead of numbers or just { index: {age}} doesn't work.
