Write a JavaScript function that returns the longest palindrome in a given string. What Is a Palindrome? Input: arr [] = {111, 121, 222, 333, 444} Output: Array is a PalinArray. To find palindrome number, we will traverse array and check each elements with its reverse number (which will be calculating in the program), if element will equal to its reverse, number will be palindrome and we will print the palindrome numbers. Thus the array is not a PalinArray. Compare the original number with the reversed number. The function should take an object where all values are Arrays and return the amount of items in all the Arrays combined together. (Use -1, -2, to indicate last, second-to-last etc . Check for Palindromes With Built-In Functions with replace() and reverse() For this solution, you will use several methods: The toLowerCase() method to return the calling string value .
