Object destructuring

Comment

Object Destructuring =>
//
   The destructuring assignment syntax is a JavaScript expression that makes it
possible to unpack values from arrays,
or properties from objects, into distinct variables.
//
example:
const user = {
    id: 42,
    is_verified: true
};

const {id, is_verified} = user;

console.log(id); // 42
console.log(is_verified); // true

Object Destructuring

Comment

const obj = { a: 1, b: 2 };
const { a, b } = obj;
// This creates two variables, a and b,
// which are equivalent to
// const a = obj.a;
// const b = obj.b;

const array = [1, 2, 3, 4, 5];
const [ zerothEle, firstEle ] = array;
// This creates zerothEle and firstEle, both of which point
// to the elements in the 0th and 1st indices of the array
