JavaScript exercises, practice and solution: Write a JavaScript program to check whether a given string is a palindrome or not using recursion.
Step 1: We have to find out if the given string is a palindrome or not. So to do this task we will create a function called isPalindrome and in this function, we will pass a parameter of string as str. So for this str, we will check the palindrome condition. Step 2: After the...
