Question

I wonder how to write palindrome in javascript, where I input different words and program shows if word is palindrome or not. For example word noon is palindrome, while bad

Answer 1

Frist I valid this word with converting lowercase and removing whitespace and then compare with reverse word within parameter word.

function isPalindrome(input) {
    const toValid = input.trim("").toLowerCase();
    const reverseWord = toValid.split("").reverse().join("");
    return reverseWord == input.toLowerCase().trim() ? true : false;
}
isPalindrome("    madam ");
//true
