Recursive Solution

function palindrome(str) {
// make all letters lowercase and remove non-alphanumeric characters
  str = str.toLowerCase();
  str = str.replace(/[^a-z|1-9]/g, "");

  // if the length of the string is 0 then it is a palindrome
  if (str.length === 0){
    return true;
  }
  // if the first letter and the last letter of the string do not equal eachother then it is not a palindrome
  if (str[0] !== str[str.length-1]){
    return false;
  }
  //Else, run the function without the first and last characters.
  else{
    return palindrome(str.slice(1,str.length - 1));
  }
}

hint [2/9]

Explanation:

You have to check if the string you get as an input is a palindrome and return true if it is, and false otherwise.

function chunk(arr, size) {
  // Break it up.
  return arr;
}

chunk(['a', 'b', 'c', 'd'], 2);

Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a multidimensional array.

function palindrome(str) {

palindrome("eye");

Return true if the given string is a palindrome. Otherwise, return false.
A palindrome is a word or sentence that's spelled the same way both forward and backward, ignoring punctuation, case, and spacing.
You'll need to remove punctuation and turn everything lower case in order to check for palindromes.
We'll pass strings with varying formats, such as "racecar", "RaceCar", and "race CAR" among others.
Remember to use RSAP if you get stuck. Try to pair program. Write your own code.

I really don’t want to hint my way out of this one, but am I on the wrong track if I’m using an if/else statement here?

I’ve learned a ton about the different functions, especially the replace function and RegEx and I just can’t seem to make it work fully.

Hey Justin101, how much of your code works right now? I'm stuck too, but only with a few examples.

maybe we can work this out together?

oh, that was yesterday. sweet
