JavaScript: Destructuring with Aliases

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables. Rather than sticking with the existing object variable, we can rename them to our own preference.

const object = { number: 10 };
// Grabbing number
const { number } = object;
// Grabbing number and renaming it as otherNumber
const { number: otherNumber } = object;
console.log(otherNumber); //10
