Tell us what’s happening:
Describe your issue in detail here.
The tests code uses the incorrect parameter for index.
[1, 1, 2, 5, 2].myMap((element, index, array) => array[i + 1] || array[0])
Your code so far

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

console.log('test')

the test description has a typo so you can just change the word index to i and you can use it to test your code.
