const colors = ['Red','Blue'];
const [first, second] = colors;

Object destructuring extracts object properties into variables.

Code:

const user = {name:'John', age:25};
const {name, age} = user;

Variables can be renamed during object destructuring.

Code:

const {name: userName} = user;

Default values are used when a property is missing.

Code:

const {city='Chennai'} = user;

Destructuring makes code shorter and easier to read.

Code:

function greet({name}) {
  console.log(name);
}
