Just experimenting with publishing a package

//Return true if the given string is a palindrome. Otherwise, return false.
function palindrome(str){
return (
    str.replace(/[\W_]/g,'').toLowerCase()===str.replace(/[\W_]/g,'').toLowerCase().split("").reverse().join("")
)
}
console.log(palindrome("not a palindrome"))
console.log(palindrome("race car"))
console.log(palindrome("A man, a plan, a canal. Panama"))

//Using regex replace whitespace or non-alphnumeric character with null/nothing
//change capital to lowercase()
//spilt(), reverse the arrays, join("")
