Write a function that accepts a string as an argument and returns true if the string is a palindrome (the string is the same forward and backward), or false if it is not.
A string is still considered a palindrome despite letter capitalization, spaces, or punctuation.
E.g.:
isPalindrome("Star Rats!"); // true
isPalindrome("palindrome"); // false
isPalindrome("I madam, I made radio! So I dared! Am I mad?? Am I?!"); // true
