Hi everyone.
I wrote the following code for this challenge:
// the global Array
var s = [23, 65, 98, 5];
Array.prototype.myMap = function(callback){
var newArray = [];
// Add your code below this line
this.forEach(function(item){
newArray.push(callback(item));
// Add your code above this line
return newArray;
})
};
var new_s = s.myMap(function(item){
return item * 2;
});
console.log(new_s);
every console.log at every point gives out the right results but for some reason I keep getting undefined when trying to log new_s. Where is my error?
Thanks in advance!
