hint [7/8]

First

function palindrome(str) {
  var normalizedStr = str.replace(/[\W_]/g, '').toLowerCase();
  var reverseStr = normalizedStr.split('').reverse().join('');
  return normalizedStr === reverseStr;
}

hint [8/8]

Second

function palindrome(str) {
  str = str.toLowerCase().replace(/[\W_]/g, '');
  for(var i = 0, len = str.length - 1; i < len/2; i++) {
    if(str[i] !== str[len-i]) {
      return false;
    }
  }
  return true;
}

Code Explanation:

We use regular expressions to replace any uppercase letter into a lowercase. Then we check if the string is the same as the reversed string using split() to split the original string by characters, then reverse and then join it back together.
