destructuring.js

//Without Array Destructuring
var nameArr = "Colin Toh".split(" ");
var firstName = nameArr[0],
    lastName = nameArr[1];

console.log(firstName); // Colin

// With Array Destructuring
var [firstName,lastName] = nameArr;

console.log(firstName); //Colin


//Without Object Destructuring
var bookShelf = {totalBooks: 10, booksType: "detective"};

var totalBooks = bookShelf.totalBooks,
    booksType = bookShelf.booksType;

console.log(totalBooks); // 10

//With Object Destructuring
var {totalBooks, booksType} = bookShelf;
console.log(totalBooks); //10
