Destructuring allows you to extract values from arrays or objects into distinct variables.

Array Destructuring:

const numbers = [1, 2, 3];
const [a, b, c] = numbers;
console.log(a, b, c); // 1 2 3

Object Destructuring:

const person = {
  firstName: "Bob",
  lastName: "Smith",
  age: 30,
};

const { firstName, age } = person;
console.log(firstName, age); // "Bob", 30

You can also rename variables:

const { firstName: nameAlias, age: personAge } = person;
console.log(nameAlias, personAge); // "Bob", 30
