Check for palindrome

Convert string toLowerCase() and use replace() to remove non-alphanumeric characters from it. Then, split('') into individual characters, reverse(), join('') and compare to the original, unreversed string, after converting it tolowerCase().

const palindrome = str => (str.toLowerCase().replace(/[\W_]/g,'').split('').reverse().join('')==str.toLowerCase().replace(/[\W_]/g,''));
