cannot find the part that refers to it

didnt know if the prev message pinged so i am sending a reply

You may be rushing too quickly through the material.

Look at the Challenges discussing map and filter.


still cannot find the code syntax
the use of func() in

function findElement(arr, func) {
  for (let i = 0; i < arr.length; i++) {
    if (func(arr[i])) {
      return arr[i];
  return undefined;

also i don’t know where the split keyword, touppercase and tolowercase was taught

You don’t need those for this exercise

This is correct usage.

These challenges are not about finding the right ‘magic syntax’. Its about using whatever syntax you want to solve the described problem.
