js destructureing code example
Example 1: array destructuring
//Without destructuring
const myArray = ["a", "b", "c"];
const x = myArray[0];
const y = myArray[1];
console.log(x, y); // "a" "b"
//With destructuring
const myArray = ["a", "b", "c"];
const [x, y] = myArray; // That's it !
console.log(x, y); // "a" "b"
Example 2: object destructuring
let a, b, rest;
[a, b] = [10, 20];
console.log(a);
// expected output: 10
console.log(b);
// expected output: 20
[a, b, ...rest] = [10, 20, 30, 40, 50];
console.log(rest);
// expected output: Array [30,40,50]
