What is an example of a correct destructuring syntax for deconstructing an object?

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: destructure to object

({x: oof.x, y: oof.y} = foo);
