javascript array dereferencing code example
Example 1: 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 2: destructuring assignment
Destructuring assignment is special syntax introduced in ES6,
for neatly assigning values taken directly from an object.
const user = { name: 'John Doe', age: 34 };
const { name, age } = user;
