Tell us what’s happening:

I feel like my code right. when i run it on live server using vs code, the checker itself works fine. when i try it in freecode camp environment I keep getting the error that checkpalidrome is undefined.

Your code so far

  // Reverse the string by splitting into an array, reversing, and joining back
  const reversedInput = cleanedInput.split("").reverse().join("");

  if (cleanedInput === reversedInput) {

Hello there!

Your project might be working with VS code, that’s because there are no instructions restrictions. I ran your code and it only fulfils three of the instructions.
