I’ve got a weird output! what is wrong I am confused.
output => 0,2,4,6
// the global Array
var s = [23, 65, 98, 5];
Array.prototype.myMap = function(callback){
var newArray = [];
// Add your code below this line
for (let i = 0; i < this.length; i++) {
newArray.push(callback(i))
}
// Add your code above this line
return newArray;
};
var new_s = s.myMap(function(item){
return item * 2;
});
console.log(new_s)
