Need guidance with (Implement map on a Prototype)

I’m really stuck here i just don’t understand how should i make the newArray as the Argument for the myMap function

// The global variable
const s = [23, 65, 98, 5];

Array.prototype.myMap = function(callback) {
const newArray = [];
// Only change code below this line
for (let i = 0; i < s.length; i++) {
// Only change code above this line
return newArray;

const new_s = s.myMap(function(item) {
return item * 2;
