deconstructing an object code example
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);

[a, b, ...rest] = [10, 20, 30, 40, 50];

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);
console.log(is_verified);
Example 3: 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 4: mdn destructuring
let a, b;
[a, b] = [1, 2];
console.log(a);
console.log(b);
Example 5: js object destructuring
