Don't use for loop

And also Array1 is a function so you should pass array nums and length to get new array.

----------

let Array1 = function (nums, k) {
//for (let i = 0; i < k; i++) {
nums.unshift(nums.pop());
//}
return nums;
};
var nums = [1, 2, 3, 4, 5];
var k = nums.length;

nums = Array1(nums, k)

console.log(nums);
