How can I add array values to an object using destructuring?

Question

I have variables here firstName which is Faisal and lastName which is Iraqi.

let str = "Faisal Iraqi";
let [firstName, lastName] = str.split(" ");
console.log(firstName, lastName);
console.log(str.split(" "));

so I should add this properties to my new object using destructuring:

let obj = {};

obj must return firstName: "Faisal", lastName: "Iraqi"

Answer 1

Simply add them to the object:

let obj = {firstName, lastName};

So the whole code looks like:

let str = "Faisal Iraqi";
let [firstName, lastName] = str.split(" ");
let obj = {firstName, lastName};
console.log(obj);

Answer 2

Instead of using a destructuring assignment as you create new variables, you can directly destructure into the object properties:

let str = "Faisal Iraqi";
let obj = {};

[obj.firstName, obj.lastName] = str.split(" ");

console.log(obj);
