Benchmark: Palindrome checker

Script Preparation code:

function checkPalindrome(input){
  return isPalindrome(input.replace(/ /g,'').toLowerCase());
}

function isPalindrome(input) {
  if (input.length <= 1) {
    return true;
  } else {
    return (input[0] === input[input.length-1]) &&
            isPalindrome(input.substring(1,input.length-1));
  }
}

Tests:

detects an empty string as a palindrome
checkPalindrome('');
detects a single character as a palindrome
checkPalindrome('a');
detects palindromic word
checkPalindrome('hannah');
detects non-palindromic word
checkPalindrome('spanner');
detects palindromic sentence with capitalisation
checkPalindrome('Mr owl ate my metal worm');
detects palindromic sentence
checkPalindrome('Never Odd Or Even');
detects non-palindromic sentence
checkPalindrome('Never Even Or Odd');
