es6 spread operator demo code example

Example 1: array spread operator in javascript

let arr1 = ['A', 'B', 'C'];

let arr2 = ['X', 'Y', 'Z'];

let result = [...arr1, ...arr2];

console.log(result); // ['A', 'B', 'C', 'X', 'Y', 'Z']
// spread elements of the array instead of taking the array as a whole

Example 2: es6 spread

const numbers = [43, 3, 11, 54];
const max = Math.max(...numbers); // Spreads numbers as parameters
// max is 54
