Tell us what’s happening:
Hello, please explain me how I can pass this. Error is "… spread operator was used to duplicate arr1."
Your code so far
const arr1 = ['JAN', 'FEB', 'MAR', 'APR', 'MAY'];
let arr2;
(function() {
"use strict";
arr2 = [].concat(...arr1); // change this line
})();
console.log(arr2);
