Destructuring practical example.

When we need to return multiple values from  a function we can return a object of having the values .But using destructure we can do this . lets see the example,

function calculateRetirement(year){

    const age = new Date().getFullYear()-year;

    return[age, 65-age];

}

const[age,retirement]=calculateRetirement(1989);

console.log(`age${age} retirement${retirement}`);
