destucture your object in js code example

Example 1: 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;
// name = 'John Doe', age = 34

Example 2: object destructuring default value

let a, b;

[a=5, b=7] = [1];
console.log(a); // 1
console.log(b); // 7
