Example 1: javascript object destructuring
let obj = {name: 'Max', age: 22, address: 'Delhi'};
const {name, age} = obj;
console.log(name);
console.log(age);
console.log(address);
let a, b, rest;
[a, b] = [10, 20];
console.log(a);
console.log(b);
[a, b, ...rest] = [10, 20, 30, 40, 50];
console.log(rest);
Example 2: object destructuring
const book = {
title: 'Ego is the Enemy',
author: 'Ryan Holiday',
publisher: {
name: 'Penguin',
type: 'private'
}
};
const {title: bookName = 'Ego', author, name: {publisher: { name }} = book, type: {publisher: { type }} = book } = book;
Example 3: destructuring objects
({ a, b } = { a: 10, b: 20 });
console.log(a);
console.log(b);
({a, b, ...rest} = {a: 10, b: 20, c: 30, d: 40});
console.log(a);
console.log(b);
console.log(rest);
Example 4: object destructuring
let a, b, rest;
[a, b] = [10, 20];
console.log(a);
console.log(b);
[a, b, ...rest] = [10, 20, 30, 40, 50];
console.log(rest);
Example 5: array destructuring in javascript
const array = ['ismail', 'sulman'];
const [firstElement, secondElement] = array;
console.log(firstElement, secondElement);
const secondArray = ['ismail', 'naeem', 'Mr', 1];
const [firstEl, secondEl, ...array1] = secondArray;
console.log(firstEl, secondEl, array1);
