Write a JS function (program) that checks if an input string is a palindrome. See what is a palindrome: https://en.wikipedia.org/wiki/Palindrome
The input comes as a single string argument.
Examples:
Input: haha
Output: false
Input: racecar
Output: true
Input: unitinu
Output: true
The output is the return value of your function. It should be true if the string is a palindrome and false if it’s not.
