Question

My Palindrome checker function works for single strings ie 'dog' it works, but when it is a phrase ie 'nurses run' it does not work! here is my code:

function palindromeCheck(string) {
  return string === string.split('').reverse().join('');

}

Answer 1

function palindromeCheck(string) {
  string = string.replace(/\s+/g,'');
  return string === string.split('').reverse().join('');
}

The s+ character means to match any number of whitespace characters (including tabs). The g character means to repeat the search through the entire string. Read about this, and other RegEx modifiers available in JavaScript here .

Answer 2

Try this.

 function palindromeCheck(string) { string = string.replace(/\\s/g, ""); return string === string.split('').reverse().join(''); } console.log(palindromeCheck('nurses run'))
