javascript destructuring nested object code example

Example 1: how to destructure complex objects

const sampleState = {
 name: “Michael”,
 age: 36,
 location: {
   state: “OK”,
   city: “Edmond”,
   postal: “73012”
 },
 relatives: {
   wife: {
   name: “Shelley”
   }
 }
}

const { age, location: { city, state }, relatives: { wife: { name } } } = sampleState

Example 2: javascript nested array destructuring

let arr = [1, 2, 3, 4, [100, 200, 300], 5, 6, 7];

// nested array destructuring
const [a, , , , [, b, ,], , , ,] = arr;

console.log(a);
// expected output "1"

console.log(b);
// expected output "200"
