Cant implement map on a prototype

[Gaa]

Tell us what’s happening:
Hi again guys! I ve been working on this challenge for a while and im a bit infuriated honestly lol. I already passed the test but im trying to do less for loops so i still want to make this work.
I dont know why this returns undefined. I ve checked this inside the push method and it still equals to the array myMap is being called on (in this case s).

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

Array.prototype.myMap = function(callback) {
var newArray = [];
// Only change code below this line
newArray.push(this.forEach(element => callback(element)))
// Only change code above this line
return newArray;
};

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

newArray.push(this.forEach(element => callback(element)))

What do you think that is going to do? What do you think the forEach returns? Get in the habit of checking the docs when you aren’t sure.

You can make this work, but you have the this.push in the wrong spot.
