Implement map on a Prototype condition fulfillment

Tell us what’s happening:
I do not know why the second condition is not fulfilled, as I have used the map method. I think there is something I am not getting.

Edit: Dang, my bad.

Your code so far

// the global Array
var s = [23, 65, 98, 5];

Array.prototype.myMap = function(x, index){
  var newArray = [];
  // Add your code below this line
newArray = => x*2);
  // Add your code above this line
  return newArray;


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