is palindrome

Comment

// Given a string, return true or false depending if the string
// is a palindrome.  Palindromes are words that read the same backwards
// and forwards. Make sure it is case insensitive!
// --- Examples:
//   palindrome("Madam") === true
//   palindrome("love") === false

function palindrome(str) {
  return (str.toLowerCase().split("").reverse().join("") === str.toLowerCase())
}
