Palindrome Checker Help

Tell us what’s happening:
I know I have a issue when I try to filter the correct characeter. I think my regex expresion is right but I don’t know if regex isn’t compatible with filter or something.

I’m missing something and I not sure what it is…

Your code so far

function palindrome(str) {
  let myFilter = str.split("").filter((i) => i == /[a-z]/gi )
  let strFilter = myFilter.join("").toLowerCase();
  let myReverse = myFilter.reverse().join("").toLowerCase();
  if (strFilter == myReverse) {
    return true
  return false;

palindrome("A man, a plan, a canal. Panama");

Link to the challenge:

You are trying to compare i with a regular expression. Regular expression are objects and i is a string. Those data types will never be equal. I think you are wanting to test the regular expression with the string i. You can write the following regular expression (without the global flag). This would test if i is a letter a-z or A-Z and return a true or false value.
